The machine I like the most is the lathe machine. It is a versatile machine tool that has a rotating spindle, a tool post, and a bed to support the workpiece. One of its main features is its ability to rotate the material while a cutting tool shapes it into the desired form. Its functions include turning, facing, drilling, and threading, which makes it very useful in metalworking and manufacturing. To operate a lathe, there are four basic steps. First, the workpiece must be securely fixed in the chuck. Second, the cutting tool is mounted and adjusted in the tool post. Third, the operator sets the spindle speed and feed rate. Finally, the machine is turned on and the cutting operation is performed carefully. Each step requires attention to safety and accuracy.

One of the most useful mechanical machines today is the cordless drill. It is a handheld power tool designed for drilling holes and driving screws into various materials such as wood, metal, or plastic. The main features of a cordless drill include a rechargeable battery, adjustable speed settings, and a comfortable handle for easy control. One of its biggest advantages is portability since it does not require a power cord, making it convenient for outdoor or hard-to-reach places. It also saves time and effort compared to manual tools. However, a cordless drill has some drawbacks, such as limited battery life and lower power compared to corded drills. In my opinion, a cordless drill is an essential tool for both professionals and DIY users because of its flexibility and practicality.

On 25 September 2025, at 10:30 AM, an incident occurred in the mechanical workshop involving Mr. Nguyen Van A, an apprentice technician. He was operating a bench grinder without wearing safety goggles. During the process, a small piece of metal was ejected and hit his eye, causing a minor injury. Fortunately, he was immediately given first aid and recovered quickly.

The main cause of the incident was the employee’s failure to follow safety rules and the lack of consistent enforcement of PPE requirements. To prevent similar incidents in the future, it is recommended that all apprentices strictly wear protective equipment, particularly safety goggles, when using workshop machines. Additional safety training sessions should be organized, and warning signs should be displayed prominently near all dangerous equipment.

Dear Nhung,

I am writing to request an advance on my salary due to an unexpected financial difficulty. Recently, I have had to cover some urgent medical expenses in my family, which has temporarily affected my budget.

I would like to request an advance payment of one million, which I am willing to have deducted from my upcoming salaries over the next two months.

In return, I am happy to provide any additional assistance to the team or take on extra tasks if needed during this period. Thank you very much for your understanding and for considering my request. I truly appreciate your support. Best regards,

Thanh

My name is Le Thanh, and I graduated with a Bachelor’s degree in Mechanical Engineering from Ho Chi Minh City University of Technology. During my studies, I gained strong knowledge in machine design, materials, and automation systems, and I am proficient in using SolidWorks, AutoCAD, and ANSYS. I also participated in several university projects and an internship at a local manufacturing company, where I improved my teamwork and problem-solving skills.I would like to apply for the position of Mechanical Design Engineer at your company because I know that your company is well-known for its innovative engineering solutions and advanced manufacturing technologies. In the next five years, I hope to become a senior design engineer and take part in developing modern, energy-efficient machines. I believe that my technical background, creativity, and strong motivation make me a suitable candidate for this position.

In the future, I would like to work as a Mechanical Engineer at a large international company such as Toyota. The company offers many attractive benefits, including competitive salaries, health insurance, paid vacations, and training programs to improve employees’ technical skills. I think these benefits help create a comfortable and professional working environment. However, I would also like the company to offer flexible working hours and performance bonuses to encourage creativity and motivation. Additionally, I hope there will be opportunities for foreign training or exchange programs to gain more experience. Among all these benefits, I prefer training and development programs the most because they help me grow professionally, learn new technologies, and become more successful in my career as a mechanical engineer.

First and foremost, as a mechanical engineer, I can help save the planet by developing eco-friendly machines that use less energy and produce fewer emissions. Furthermore, I can design renewable energy systems, such as solar-powered engines or wind turbines, to reduce dependence on fossil fuels. Besides, in my daily life, I will try to use public transportation, recycle materials, and save electricity whenever possible. I can also promote green technologies and encourage others to apply sustainable solutions in their work. In addition, I will continue to research new materials and technologies that improve energy efficiency. Last but not least, I will take responsibility for protecting the environment by combining my technical knowledge with practical actions to create a cleaner and more sustainable future for our planet.

One useful device that uses alternative energy is the solar-powered water heater. It uses solar energy instead of electricity or gas to heat water. This type of energy is clean, renewable, and environmentally friendly because it does not release harmful gases into the atmosphere. The system operates by using solar panels to absorb sunlight and convert it into heat, which warms the water stored in a tank. This device is especially popular in sunny countries because it helps reduce electricity bills and protects the environment at the same time. However, one problem with using solar energy is that it depends on weather conditions. On cloudy or rainy days, the heater may not work efficiently, so a backup heating system is sometimes required.

One amazing device that uses smart technology is the autonomous car, which belongs to the transportation field. It is operated by an intelligent control system that uses sensors, cameras, and artificial intelligence to detect obstacles, read traffic signs, and make driving decisions automatically. This smart vehicle can be used in big cities or long-distance travel to make transportation safer and more efficient. It brings many benefits to people, such as reducing traffic accidents, saving fuel, and minimizing human errors. Furthermore, it helps disabled or elderly people travel more easily without depending on others. In the future, autonomous cars will help solve serious problems like traffic congestion and air pollution, creating a smarter, cleaner, and more convenient transportation system for everyone.

In the future, I want to live in a smart house by the beach where I can enjoy both comfort and nature. My smart house will be equipped with voice-controlled lighting, automatic doors, a smart security system, and energy-saving solar panels. It will also have smart sensors that adjust the temperature and lighting based on the weather and my daily habits. The advantages of this house are convenience, safety, and lower energy costs. However, one disadvantage is that it requires high maintenance and internet connection to operate properly. I plan to live there with my family, so we can enjoy a modern and comfortable life together. I want to live in this smart house because it provides peace, efficiency, and environmental protection for a better future.
