One machine I like the most is the lathe. A lathe is a versatile machine tool used to shape metal or other materials by rotating the workpiece against a cutting tool. Its main features include a strong bed, a headstock with a spindle, a tailstock, and a carriage that moves the cutting tool precisely. The lathe is commonly used for turning, facing, drilling, threading, and taper cutting. There are about five main steps to operate this machine safely. First, the operator must check the machine and wear protective equipment. Second, fix the workpiece firmly in the chuck. Third, select the correct cutting tool and adjust the speed. Fourth, start the machine and move the tool carefully to cut the material. Finally, stop the machine and measure the product to ensure accuracy.

A smart device that is widely applied in the medical field is the smart wearable health monitor. This device is used in hospitals and also by individuals at home to track vital signs such as heart rate, blood pressure, and oxygen levels in real time. It operates through built-in sensors and connects to a smartphone via wireless technology, allowing data to be stored and analyzed instantly. Doctors can access this information remotely to monitor patients’ conditions and make timely decisions. The main benefit of this device is that it helps detect health problems early, reducing the risk of serious complications. In addition, it saves time and cost for both patients and healthcare providers. Overall, this smart technology improves the quality of medical care and supports a more efficient healthcare system.

The machine I would like to review is a CNC router. This machine is widely used in mechanical workshops for cutting, engraving, and shaping materials such as wood, plastic, and even aluminum. It is equipped with a powerful motor, a stable frame, and a computer-controlled system that ensures high precision and repeatability. One of its main advantages is its ability to produce complex designs quickly and accurately. In addition, it saves time and reduces manual labor. However, the CNC router also has some drawbacks. It can be quite expensive, and the assembly process may take several hours. Moreover, beginners may find it difficult to operate at first. In my opinion, it is a very useful and efficient machine for both hobbyists and professionals.

Dear Mr. Johnson,

I hope you are doing well. I am writing to respectfully request an advance payment due to some unexpected financial difficulties. Recently, I have had to cover urgent medical expenses for a family member, which has significantly affected my budget this month.

I would like to request an advance of $800 from my upcoming salary. I assure you that this amount can be deducted from my next two paychecks as convenient.

In the meantime, I remain fully committed to my responsibilities and am willing to take on additional tasks or provide extra support to the team if needed.

Thank you very much for considering my request. I truly appreciate your understanding.

Sincerely,
Huy Tran

As a mechanical engineer, I believe I can take meaningful actions to help save the planet. First and foremost, in my daily life, I can reduce energy consumption by using public transport, saving electricity, and recycling materials whenever possible. First of all, I should also raise awareness among friends and family about environmental protection. Furthermore, in my job, I can design energy-efficient machines and systems that consume less fuel and reduce emissions. Besides, I can support the use of renewable energy technologies such as solar or wind power in industrial applications. I can also focus on improving manufacturing processes to minimize waste and pollution. Last but not least, I will continue learning and innovating to create sustainable engineering solutions for a greener future.

One device that helps protect the environment is a solar-powered water pump. It uses energy from the sun, which is a clean and renewable source of power. I choose this type of energy because it does not produce harmful emissions and is available almost everywhere, especially in rural areas. The system operates by using solar panels to convert sunlight into electricity, which then powers a motor to pump water from underground or nearby sources. This machine is widely used in agriculture for irrigation. However, there are some problems with this alternative energy. For example, the pump depends on sunlight, so it may not work efficiently on cloudy or rainy days. In addition, the initial cost of installing solar panels can be quite high for some users.
