PT Scaffolding Activity 12-F by Alesi Terrell Villanueva https://padlet.com/s2014329/m7os The motorcycle service provider, Angkas, proposed a backpack-like shield in response to the fight against COVID-19 for back riders. The design was then approved by the IATF, which drew criticisms from netizens and engineers. However, the idea was later on dismissed by the government after days of implementation. I wonder how your class can make this padlet informative using news articles, books, and information from current digital technology platforms to provide a sound explanation for the public why this design is not safe at all. en-us 2020-09-14 06:19:41 UTC 2020-09-21 15:50:00 UTC hello@padlet.com https://padlet.net/icons/png/1f6f5.png Rabe, Anastacia R.

Given this, the stability of the motorcycle will be affected and of course the safety of the rider himself/herself.]]> 2020-09-15 12:18:07 UTC https://padlet.com/s2014329/m7os/wish/747400780 Maranan, Casey Marie L. - Time: 6:17PM s2008021 https://padlet.com/s2014329/m7os/wish/758214852 The implemented backpack-like shield is not safe because the partner rider does not have a proper place to hold on to. The item has 2 handles at the back which is meant for holding but this is not enough to protect the partner rider from falling backwards. If we place this in a car situation the handle is like the seatbelt. If a car suddenly breaks after moving with high velocity, the seatbelt is enough to make sure the passenger won’t fall over the glass (lessens the force impact). As for the motorcycle, the handle could be easily let go off or the backpack-like shield could not be stable and fall with the passenger. If the motorcycle suddenly stops, a person with a large mass could not depend on the shield for safety. He/she will fall off and just harm themselves.]]> 2020-09-18 10:17:19 UTC https://padlet.com/s2014329/m7os/wish/758214852 Bacal, Bridgette Irish C. - Time: 10:33 AM s2013454 https://padlet.com/s2014329/m7os/wish/760635744 While the backpack-like shield promotes or finds a way for commuters to adjust to the new normal, it is not entirely safe. One of its problems is that the barrier can affect the motorcycle’s aerodynamics, which is A LOT MORE complex compared to that of a car. There is already a high risk of motorcycles being prone to accidents, and this is because the motorcycle that moves through the air interrupts this, because of its irregular shape as compared to a car. Turbulence occurs, and this is what holds riders back in motorcycles and friction is created to push against the object in motion. This causes an aerodynamic drag, which is affected (as this is the force parallel to the direction of the flow). The stability of the motorcycle ends up at a risk, and the shield itself contributes to the odd shape that breaks up the smooth path of air.]]> 2020-09-19 02:33:04 UTC https://padlet.com/s2014329/m7os/wish/760635744 Maranan, Casey Marie L. - Time: 1:13PM s2008021 https://padlet.com/s2014329/m7os/wish/760717575 The backpack-like shield is not enough to hold the passenger rider while the motorcycle is in motion.

Time: 3:41 PM s2013936 https://padlet.com/s2014329/m7os/wish/760777144 According to Mel Aquino, a riding coach of Mel Aquino’s Yamaha Offroad Training Camp, the rider must always wrap around the waist of the driver. This is because both the rider and the driver should act as one the entire ride. The driver should always be in control of the motorcycle because any sudden movements would influence the stability and control over the motorcycle. For instance, if the back rider does not lean with the driver in motion-cooperation, this would affect the driver’s control. Thus, given the Angkas backpack-like shield that has small handles at its bottom, it is not safe enough for both the rider and driver of the motorcycle.]]> 2020-09-19 07:40:37 UTC https://padlet.com/s2014329/m7os/wish/760777144 Garcia, Kassandra J.

One may be the safety of the passenger. Yes, this creative inventions makes us safer as we go out in public during the pandemic, but that wouldn’t help lessen the amount of accidents being brought upon a motorcycle — if so, it only makes rides more dangerous. Motorcycles are dangerous as it is, considering the open aired often uncontrollable acceleration but having this barrier in the middle of the passenger and driver will make it more dangerous for the passenger in a sense where the passenger isn’t as secure as if there was no barrier. Not being fully secure will help rise the amount of accidents related to motorcycle drivers and passengers. ]]> 2020-09-19 13:33:39 UTC https://padlet.com/s2014329/m7os/wish/760948289 Enriquez, Kimi Alexa C. - Time: 9:53PM s2015548 https://padlet.com/s2014329/m7os/wish/760961903 After several research, I can conclude that a backpack-like shield as proposed by the motorcycle service provider, Angkas, is not considered the safest option because although it does help us adjust to the “new normal,” it may actually end up compromising the safety and heath of both the driver and the passenger more. According to the Philippine Society of Mechanical Engineers Inc., such invention is considered unsafe considering the vehicle itself and the motion it produces causing greater risk to the rider and passenger’s safety and health. They also stated that because of the barrier, it can cause pressure to build up leading them to accidents and there is no full guarantee that the barrier is effective in protecting the spread of the air particles from the rider and passenger.]]> 2020-09-19 13:53:08 UTC https://padlet.com/s2014329/m7os/wish/760961903 Enriquez, Kimi Alexa C. - Time: 9:55PM s2015548 https://padlet.com/s2014329/m7os/wish/760963322 Sunstar.

Motorcycles are already highly accident-prone and with this shield. With the instability of the motorcycle, this will affect the safety of not only the driver but also any passengers.

It was supposed to be a backpack-like shield that would lessen the possibilities of motorcyclist getting COVID-19. However, there were several cases of motorcycle accidents that happened due to the backpack-like shield.

  • Removal/dismissal of these backpack-like shield. 
  • If in all cases that it is still required for motorcycle services to have this backpack-like shield, we should demand for a better/safer design of this shield. The next design should limit the aerodynamic drag the driver and passenger receives during a trip from one destination to another. This application of reducing the aerodynamic drag would lessen both wind dragging and wind lifting the driver would receive thus lessening possible road accidents. Ways to improve the design is through looking at the evolution of cars. Modern cars are improved in designs throughout the decades not only by making it prettier but in terms of reducing the aerodynamic drag it receives. Modern vehicles designs that reduces the aerodynamic drag is through the smoothness and overall shape of the vehicle (reducing having rough edges). From this, the next backpack-like shield must have smooth edges, shorter in height, and must not be wider than the driver.

    - 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.]]>     2020-09-21 05:49:53 UTC https://padlet.com/s2014329/m7os/wish/763100518     Rabe, Anastacia R.

    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. ]]>     2020-09-21 10:26:40 UTC https://padlet.com/s2014329/m7os/wish/763603046     Regis, Psalm Darius C. https://padlet.com/s2014329/m7os/wish/763604113 Time: 6:28 pm

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.

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.]]> 2020-09-21 14:53:36 UTC https://padlet.com/s2014329/m7os/wish/764494028 Deang, Raven https://padlet.com/s2014329/m7os/wish/764496902 Rosales, B.

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.]]> 2020-09-21 15:29:42 UTC https://padlet.com/s2014329/m7os/wish/764676552
