Hi my name is Tuyen and today, I would like to talk about how to use a drill safely. As you can see, there are two stage. The first stage is to prepare a drill and the second stage is to drill safely.

In the first stage, you need to remember 7 steps.

First one, you need to wear safe clothing and eye protection. It protect you from the chip or dust.

In step two, remember to wear ear protection if drilling regularly because a handheld electric drill can cause earing damage after prolonged exposure.

The third step is that you should wear breathing protection. It protect your lungs.

Next one, choose the correct drill bit because using a bit made from the wrong material can cause the bit or the material you’re drilling to break.

Moreover, fit the drill bit firmly into the chuck. Make sure the bit is straight and secure.

After that, clamp small pieces firmly together. Do not hold the piece down with one hand while drilling, as the drill could slip and injure you.

The final thing you should remember is that you should handle the cord safety.

In the second stage, you need to remember 5 steps.

Firstly, drill a pilot hole because it will help prevent your drill bit from slipping, and reduces the chance of splitting wood or other damage.

Secondly, drill with steady pressure. Remember to hold the drill steady and push it into the material you’re drilling.

Next, adjust the clutch. Look at a series of numbers on drill, you can lower or higher the torque.

Besides, avoid overheating the drill bit

Finally, do not force a jammed bit through. If the drill bit gets stuck in the material, don’t try to force it out by running the drill. Unplug the drill, separate the bit and the chuck, and remove the bit using manual tools.

That at all about how to use a drill safely.

Now I'd like to share some details about SolidWorks 2021 with you. It's a robust, user-friendly, and sophisticated CAD program. It comes with a lot of features. Firstly, it helps examine the designs for any structural weaknesses. Secondly, the users can isolate any problems and improve them before physical designs are made. Besides, it has some advantages. SolidWorks 2021's initial benefit is that it allows users to save money on prototyping and testing. Another benefit is that it is inexpensive, with discounts available to students. It really does, however, have a few disadvantages. The subscription, for example, costs a few thousand dollars each year and is not available on Mac. Finally, I believe it is a reasonably priced expert CAD program that is also well suited to students.

Tuyen is my name, and I work for Hyundai as an apprentice. I'm going to write a new report regarding an incident that occurred last week at our job. The injured individual is Peter, a 27-year-old man. He worked as a welding engineer in our company's welding facility. On December 20th, about 8.30 a.m., an incident happened at Workshop 3. He was welding when he suddenly couldn't open his eyes, his eyes pained, and his left hand was burned. After investigation, I determined that he neglected safety rules and forgot to wear a proper welding helmet and a pair of welding gloves. To avoid such tragedies, I propose that our organization produce a corporate manual outlining all welding safety requirements in the workplace.

Dear Miss Huong,

My name is Tuyen, and I work at Foxconn as a design engineer. Prepayment inquiries should be sent to this email address.

I typically work away from home, but because I don't own a car, I have to rely on public transportation, which makes my working time shorter and less effective. I'd want to get a new motorcycle, but I don't have the funds at this time. I was hoping to get paid ahead of schedule.

It's a thousand and five hundred bucks. Getting a new motorcycle costs too much for me.

I sincerely hope you will be able to assist me, and I anxiously anticipate your response.

Thank you very much.

I graduated from the Hanoi University of Industry. In the year 2022, I received my diploma. Now I'm a mechanical engineering bachelor's degree holder. I have a lot of experience and accomplishments up to this point. For example, I am knowledgeable on CAD software, Microsoft Office,... I am fluent in both English and Japanese. When I saw Hyundai job posting on timviec.com, I wanted to join the firm as a maintenance engineer and work my way up to become a maintenance leader in the following five years. I believe my qualifications are enough for this post. As far as I'm aware, Hyundai has a fully digital vehicle plant with cutting-edge production technology controlled by robots. Furthermore, this business has good remuneration for employees, such as private healthcare, an annual bonus, and a pension scheme. Therefore, I want to apply for the position of maintenance engineer at a welding workshop advertised on timviec.com because I believe I can do this job well with my qualifications and skills.

Our Earth is confronted with several environmental issues, including:

Storms, hurricanes, volcanoes, and floods are examples of natural calamities that pollute the air and water. So, what can we do to help rescue the environment? As a regular citizen and a mechanical engineer, I'd like to provide some suggestions.

To begin with, even the tiniest actions in our everyday lives may help safeguard the environment.

We can save power by shutting off lights when we are not using them, for example.

Second, rather than driving our own cars, we may take public transportation. We should also recycle plastic bags and bottles.

As a prospective mechanical engineer, I believe I should pay attention to the solutions listed below. First and foremost, I will make every effort to develop a new alternative energy source. Second, I'll create devices that use alternate energy sources. Third, I will urge everyone to work together to create a clean and green environment in order to rescue the planet in the next few years.

Finally, I believe that we should do any of the above to safeguard our environment.

My ideal smart house would be both environmentally friendly and appropriate for someone my age. Security, in my opinion, is one of the most crucial aspects of the house of the future. I believe so because criminals will not be able to gain access to or break into our home if we own it. My smart house also features fingerprint lock technology, which means that burglars won't be able to cut or break it like they can with standard locks. Furthermore, the artificial intelligence technology in my house allows me to operate my home's electronics with my voice or motions. For example, if I want to take a shower, it will set the room temperature to my preference and change the water temperature accordingly, or it will darken the windows at night and lighten them when you get up in the morning without the use of curtains. All of the equipment in my smart home, on the other hand, is constructed in a contemporary manner using eco-friendly and energy-saving recycled materials. It will, in my opinion, assist me in paying less for energy. This type of house appeals to me because it has the potential to make our lives easier and more pleasant.

Today I would like to introduce to you a device used to create artificial light that is a giant mirror floating in space. It is applied in the field of energy technology for the purpose of replacing the current types of light-emitting devices that use current types of energy that can cause environmental pollution and inefficiency, such as gas, electricity, oil, etc. The mirror is about 60 meters in diameter and is used as a second sun that shines at night. The mirror works by accumulating sunlight during the day and then emitting it at night. It will bring great benefits to people because it completely saves a lot of the cost of star lighting with an electric bulb. I predict that this technology will be completed and put into practice in the next 20 years.
