The Angkas "Back Shield" proposal was supposed to be a way for people to gain income while also avoiding direct contact with their clients while riding to prevent the transmission of the Covid-19 Virus. The issue with this solution is that it compromises the safety of those riding the vehicle. The shield, while offering some sort of indirect contact to prevent transmission, can cause the vehicle to crash due to a change in aerodynamics and the overall clunky-ness of having somebody tugging at your back while you drive.

# data[].attributes.body
It is much safer to remove the backpack-like shield due to the possible implications. The best solution is to make it mandatory that both the driver and passenger wear masks or just stop using motorcycles as it has been statistically proven to be the most unsafe mode of transportation.

According to one of the members of the Philippine Society of Mechanical Engineers, when the motorcycle is in motion, the barrier attached to either the motorcycle or the rider or the rear-wheel drive would increase the aerodynamic forces and increase the drag and lift beyond the limit for the vehicle, thereby destabilizing the motorcycle and endangering both.

A solution to the Covid-19 crisis must be practical, affordable and effective . The observance of basic health protocols like wearing masks, frequent washing of hands, or use of disinfectants must likewise be maintained. A structured physical barrier is not necessary.  I suggest that the we should strictly focus on more functional and sensible for both riders and passengers.

# data[].attributes.body
The rider should always be in control with the bike. If the passenger will not cooperate with the motion of the rider, any sudden movement will affect the rider’s control. The passenger greatly affects the weight distribution of the motorcycle.

# data[].attributes.body
Although Angkas proposed the use of these plastic shields for safety measures to persuade the government to resume operations this product does not provide certainty that it is safe from preventing the viruses to inflict a person. Based on the design of this shield, we should consider the weight of the shield and  aerodynamics applies to the scenario when in motion.

# data[].attributes.body
In relation to aerodynamics, the rider is holding on tightly to prevent himself being pushed back by the airflow, he is also extending the forks and raising the front end slightly. At the same time, wind pressure hitting the unprotected rider (due to small space and imbalance) is causing the rear suspension to sit slightly. Raising the front and lowering the rear causes instability.

# data[].attributes.body
In place of the back-riding plastic shields that may pose a considerable risk to both the passenger and driver, the implementation of the proper use, treatment, and sanitation of masks, face shields, and other protective gear should be enforced instead. Executing simple precautions effectively can considerably reduce the risk of transmission. Other precautions such as mass testing and strict clearance for public certifications such as identification cards and quarantine passes may be practiced. 

# data[].attributes.body
The platform that should be used to spread this plan would require social media for the progression of information will increase.

Air is considered a factor to the scheme. Once the motorcycle is in motion air may be contaminated with various of viruses

It would cause severe impact on the ride. The first cause would be why the driver lost his balance due to the weight of the barrier and may cause a complication

# data[].attributes.body
In the field of aerodynamics, the barrier would be the source of aerodynamic drag. It is defined as the force of an object that resists its motion due to gases.

# data[].attributes.body
Due to the different conditions that dawned upon society by the global pandemic, COVID-19, several different solutions have been made to fit the virus's problems. Different transportation businesses, like Angkas, have been innovating creative ways to provide service to the public while taking the proper precautions. However, after analyzing the back-riding plastic shield proposed by Angkas, some issues have been found, which may cause more danger than it does good. The faulty design comes hand in hand with aerodynamics when considering the driver's mobility and maneuvering control. 

# data[].attributes.body
Angkas proposed a backpack-type barrier worn by the driver to the fight against COVID-19 for back riders. The proposal may have good intentions, but unfortunately, it might also be dangerous. The main reason is that both the rider and their passenger should act as one during the entire ride. If the passenger, for example, doesn’t lean with the rider, the motorcycle may become unstable and eventually lead to the rider losing control of the bike.

# data[].attributes.body
Aerodynamics plays a vital role as a concept that turns down the project of implementing the back-riding plastic shields. To be specific, air resistance is a force that acts against an object that is moving through air. Suppose the motorcycle was to move in a direction that goes against a decisive blow of wind. In that case, drivers could quickly lose control and balance over their motorcycles due to differences in friction and air pressure. This decreased control over the vehicle worsens due to the plastic barrier, which adds more surface area that the air comes in contact with. As a result of this interaction, an aerodynamic concept called drag, which is an unavoidable effect of moving through gas, occurs. The drag and air resistance may also vary depending on the plastic barrier's final shape and size.

One reason why the proposed plastic shield project may pose a threat is its faulty design. Due to the wearable, backpack-like design, there would be more added and unbalanced weight on the driver, which would interfere with the driver's control. If the passenger refused cooperation, any sudden movement or restriction on the shield could render the motorcycle uncontrollable for the driver.

The driver should just wear a face shield, double face mask, and gloves to prevent the spread of COVID-19. The service provider should just provide their riders with all these safety wear. I don't think that there is a need for the backpack-like shield. If the riders and passengers will be responsible enough to wear these, then it will prevent the spread of the virus.

# data[].attributes.body
If ever this backpack like shield is still going to push-thru. Its best to get results and feedback from professionals to see the effectiveness before mass production. If we were looking for alternatives, we could use better protection for our face, hands, etc.

# data[].attributes.body
Ineffectiveness could also be a factor that wouldnt make this backpack like shield a good response to this situation. Suppose that the driver or passenger shows symptoms whether mild or not, we arent sure if it'll spread to the other person.

# data[].attributes.body
Most people are not used to holding on a backpack-like shield when they are a passenger on a motorcycle, most people are used to holding on to the driver. So the passenger might be pulling too much on the backpack-like shield which can lead to a fall because the driver will also lose balance due to too much leaning, especially when the driver is coursing through traffic or going fast.

# data[].attributes.body
When turbulence occurs, a friction is created that pushes an object to the opposite direction. When friction potential is exceeded, motorcycles can become very unstable that can cause a motorcycle to fall.

# data[].attributes.body
A lopsided load makes the motorcycle harder to handle, it also affects the performance of the driver and requires more energy from the driver. So adding more weight like the backpack-like shield is dangerous. The motorcycle is easier to handle if the weight is as low as or close to the motorcycle.

# data[].attributes.body
The proposed backpack-like shield in response to the fight against COVID-19 for back riders by Angkas is not safe at all because wearing this backpack-like shield adds more weight to the driver, which will make it harder for the driver to balance. That affects the aerodynamics of the motorcycle, and also the stability.

The backpack-like shield wouldn't be effective in terms of protecting both riders. The front side of the barrier builds up pressure because of an air vortex, which creates turbulence behind the barrier. Which could cause more injuries whenever an accident occurs.

# data[].attributes.body
Instead of using backpack-like barriers, a more effective way to minimize the spread of the virus is to use protective gears such as full faced helmets both for the driver and the passenger

# data[].attributes.body
Considering air-resistance, installing the barrier would cause the motorcycle to an unbalanced state of motion and would increase the risk of crashing and even death.

# data[].attributes.body
The backpack-like shield of the driver can possibly build up pressure, weight and cause instability. Which would cause a risk or accidents to both the passenger and driver.

# data[].attributes.body
The installation and implementation of backpack-like dividers is not safe because it can increase hazard exposure to both the driver and the passenger. The divider would create air resistance, this could affect the maneuverrability and can cause destabalization to the aerodynamics of the motorcycle. The motorcycle disposes the risk of imbalance.

# data[].attributes.body
The country, along with other countries all over the world is in a battle with sustaining the economy and by all means we should find new, creative and effective ways to adapt to the new normal. The Angkas face shield is a stepping stone for new innovation, and with a better system we can have a safer and less worrisome environment for both both drivers and passenger.

A suggestion would be to implement a better payment system that would eliminate the close interaction after the ride. Next would be to come up with a design for the shield that will fix the aerodynamic problem. Lastly would be to have a good practice of proper hygiene and to follow the safety protocols, the use of hand alcohol and face mask, before and after the ride could make a big difference. These might be significant changes but it is what we have to do protect ourselves and the people around us.

# data[].attributes.body
The overall safety of both driver and passenger is what matters and even if the shield will do its job, if any of the them is vulnerable the virus will cling on to them. The virus has no pick, if you do not follow the safety precautions of social distancing and wearing a clinical face mask, the shield will not matter.

Instead of using barriers like make-shift shields for protection against infections, This idea can minimize accidents and infections without forcing people to make big investments to continue their income.

Use a different type of vehicle as a "taxi service". Using motorcycles has a big disadvantage being the fact that you NEED to be close to each other in order to safely, and comfortably ride it from point A to B. A car is easy to use for this situation because you can have the front seats closed off so that only the back seats can be use creating enough distance away from the rider and the driver minimizing the contact. That being said, not everybody can afford a car to use as an ankas. Therefore the next best solution is a tricycle car with a transparent plastic barrier in-between the driver and rider. This should minimize the risk and more importantly contact between the two people. Having the payment be done with a compartment in the tricycle car.

# data[].attributes.body
The aerodynamic features of the shield seems to not have been thought-out, the design takes up a lot of space that will surely act against the wind force when the vehicle is moving. The potential of an imbalance force against the driver could cause some serious accidents.

# data[].attributes.body
The safety shield is mounted at the back of the driver and forms a shield like structure limiting the interaction between the passenger and driver which by all means is a well thought-out concept. The problem I notice is the weight distribution of the shield would have a huge effect on the driver and the vehicle in general as wind will be an added factor of force against them.

The shield is light, weighing at 0.63 kg. If the motorcycle moves at high speeds, the shield might catch air resistance in the opposite direction; in other words, it will act like a sail. This possibility, along with the shield's small mass, can destabilize the motorcycle; thus, accidents may happen.

The implementation of the safety shield has been a new way for public transportation vehicles to comply with the government's regulations and protocols during this pandemic while still earning.

Instead of the backpack barrier implementation a simple helmet with some covers and protection would be enough to protect the drivers and the passengers from contacting the virus.

# data[].attributes.body
The backpack barrier will disturb the aerodynamics of the motorcycle which will make the motorcycle unstable which will result to a crash. Disturbing the aerodynamics can also result in adding drag and lift which can result in to a crash.

The backpack barrier is strapped to the driver and not to the motorcycle which will make the barrier unstable especially in motion. The passenger can outbalance the driver which can cause the driver to crash.

# data[].attributes.body
Due to COVID19 transportation has been adjusted especially in motorcycles. Angkas has proposed a backpack barrier that would be used to protect the driver from contacting any person from the virus. The barrier is acceptable but with few minor flaws in the design. The problem with the barrier is that the balance of the passenger relies on the driver because the passenger needs to hold on backpack barrier when in motion. Aerodynamics will be affected in motion.

# data[].attributes.body
Instead of implementing a backpack like shield that compromises the safety of the riders, a helmet will do.

But:
- the helmet must have a specific design :
- the helmet must cover the entire head
- the helmet must be shock proof

# data[].attributes.body
Air resistance
- With the addition of the backpack like shield. When the motorcycle is in motion, the barrier will trap wind/air into it, thus creating pressure. With this, there is a high chance that the rider will be carried by the wind and the motorcycle being hard to control and lose its balance resulting to an accident.

Inertia
- According to Newton's First Law of motion, "An object at rest will remain at rest unless an unbalanced force will act upon it"
- (inertia) The tendency of an object to maintain the same state of motion.
- Example : Car with people inside. As the car accelerates, the people tend to lean backwards, and as the car comes to a stop, the people tend to lean forward
- To connect : since there is a barrier (backpack like shield) attached to the rider, instead of staying balanced with the motorcycled, the rider instead, will most likely fall and push the passenger (if there is) with him/her because as the motorcycle moves forward, the rider and passenger will move backward because of the pressure created by the shield.

# data[].attributes.body
The Philippine Society of Mechanical Engineers said: "when the motorcycle is in motion, the barrier will contribute to the change of the designed allowable aerodynamic forces (DRAG AND LIFT) which will compromise the stability of the motorcycle. This will place the safety of the riders at risk.

# data[].attributes.body
The simple full-covered helmet can be already enough to be a requirement for a rider as well as a fixed sanitizer from the driver to regularly spray in every ride. Another rule that would be best to implement would be bringing your own helmet. As we know, passengers use the provided helmet by the drivers, but as we are in a pandemic, that would be more dangerous than not wearing it. If it cannot be avoided, the driver should prepare at least two extra helmets so that every time one has been used, it can be sanitized and left to dry so that it can be used again later on.

# data[].attributes.body
If this shield will be used, the consultation of engineers must be done before applying the shield to the motorcycle. Also, helmets must be used at all times and that to prevent accidents and injury.

# data[].attributes.body
Implementing this backpack like shield could cause harm to the health of both the driver and the passenger. The weight, size, as well as balance are factors that can cause a crash or other harmful accidents to the driver and passenger.

# data[].attributes.body
Aerodynamics
- According to the Philippine Society of Mechanical Engineers Inc. The backpack like shield is not safe because when the motorcycle is in motion, the front side of the barrier builds up pressure creating a turbulence and suction behind the barrier.

# data[].attributes.body
The second reason for why this shield is not going to be the safest for riders is because there will not be enough space for the rider to hold on to due to the size of the shield. The rider will not be able to lean the same way as the driver, which will help the bike maneuver quicker in tight spaces. If the rider and driver will not be able to lean the same way as the driver, it might cause the bike to lose balance and end up to an accident.

# data[].attributes.body
Due to the addition of backpack-like shields, riders are being deprived of proper handles or support to keep them balance and in control of themselves on the ride. It is a must that the back rider should at least hold the riders waists or shoulders, but with the shields on the way, the shield handles wont be enough and may bring problems for stability.

Improving the barrier design will be better for everyone because as said implementing this can result to potential accidents that can result to death or grave injuries. Consulting engineers can help them find a better design or find a new innovation to implement in social distancing that will have less effects and give more benefits to people.

Having the back pack shield will also affect the mobility of the motorcycle. It will be much harder because of wind resistance this will affect the maneuverability of the vehicle making it harder to turn, accelerate etc. Secondly, implementing this will also affect  the passengers because they will have nothing to hold on while riding and this will result to a potential accident.

During COVID-19, social interaction is limited and social distancing is what we need. Us Filipinos are known to be sociable, which makes it difficult for people to stay at home. Although, one of the more important reasons why people have to leave their homes is to work. In addition to this, most Filipinos also commute instead of taking private vehicles. One of the known service providers is Angkas, which uses a motorcycle. They proposed a backpack like shield to prevent the transmission of the virus.

However, having seen that it gives more dangers instead of benefits, it is important to come up with a better plan. First and foremost, the backpack-like shields must be obliterated, and instead helmets that will be FULLY closed. The rider and the passenger must use masks that have layers for full safety. The helmet also has a purpose of protecting the head of both people should there be an accident since it lessens the impact.

The barrier can catch wind, causing the speed and movement of the motorcycle to be pulled back. In addition, the backrider would need to shift towards the same direction as the rider in order to maintain balance, otherwise, an accident may occur.

# data[].attributes.body
Recently, Angkas proposed a backpack-like shield to respond to the pandemic for the back-riders. As the main purpose of this design is to protect the back-riders, I believe that the shield will actually do more harm than good. My main reason is due to Newton's First Law of Motion or Inertia.

# data[].attributes.body
Remove backpack shields and opt for using full-head helmets instead. Not only will this prevent spreading of the virus, but it will also prevent injury and impact to the passengers’ head in case of collisions (where they are thrown forward or back.

# data[].attributes.body
Newton's First Law of Motion (Inertia). As said in previous explanations, the passengers have limited to nothing to hold on to. Due to that, the passengers behind the barrier will stay more in motion, rather than the driver and the motorcycle. Meaning, as the motorcycle accelerates, turns or decelerates, the passenger will more likely fall backwards, sideways, or injure himself on the barrier itself.

According to the Philippine Society of Mechanical Engineers (PSME), it has stated that the barrier may negatively contribute to one’s safety, health, economy and the environment.

- it will affect the stability of the motorcycle since the barrier significantly changes its aerodynamic forces or its drag and lift.

The backpack-like shield compromises the safety of both rider and backrider because the shield changes the aerodynamics forces, drag and lift (Singson, 2020). The changes of these aerodynamic forces affects the stability of the motorcycle making both rider and backrider prone to road accidents.

I would remove the backpack shields because it is just gonna cause more harm than help. I would rather suggest the riders to use a face shield instead since it just does the same job while designing a better shield for the meantime until a better backpack shield design is released

Nowadays, a lot of companies are trying to conceptualize different ways to work against the COVID-19 pandemic. Angkas has proposed a backpack protection that would be used to protect the driver and passenger from contracting the virus. This design may seem innovative and good to some, but there are also downsides towards this approach. One of these reasons are because it will give the passenger lesser space to hang on to the bike. However, the main reason is because it will affect the aerodynamics of the bike and will affect the stability of the bike, and will make it much more difficult for these motorcycles to maneuver through traffic.

Many companies and institutions have been thinking of creative ways to respond to the COVID-19 situation. The motorcycle service provider, Angkas has proposed a backpack-like shield that will be used as protection against this disease. It may seem like a very new and innovative method however, this design is very harmful and may have more risks than benefits. This design will harm the passenger as it is not safe and fully secured. When the motorcycle is in motion, there may not be an area wherein the passenger can hold onto the vehicle.

Due to the situation we are in right now. We still need to prioritize social distancing. The shield barrier is easy to make and buy. The price of shield barrier is around 600-1500 pesos which is an affordable price for the people who rides motorcycles. Shield barriers may help you go from one destination to another, however. Having shield barriers may also lead you to an accident.
