I am studying at Hanoi University of Industry, very close to your school, so I would like to invite you to come over. I attend the school's 4-year course, I don't work part-time and spend all my time studying. I study mechatronics and will get an engineering degree when I graduate. Currently my main subjects are general subjects and for me English is the most difficult subject because I am very bad at English. On the contrary, I really like physical fitness, a week I have 6 classes from Monday to Saturday. After class I always try to self-study and join clubs to help improve myself. I love my university!
Looking forward to seeing you at my university soon!

I’m an inspector from Quality Control department in Samsung Company. Yesterday, I checked your product – the shaft and found some design mistakes. In the design drawing of the shaft, it is 50 millimeters plus or minus 0.25 millimeter and the length of the actual shaft is 50.05 millimeters. It is inside tolerance. Next, the diameter of the shaft in the drawing is 6.010 mm plus or minus 0.004 mm, so the minimum diameter of the actual shaft is 6.006 mm. But its actual diameter is 6.000 mm and it is out of tolerance. Finally, the hole depth of the shaft varies between 9.75 mm and 10.25 mm. And the actual hole depth is 10.30 mm. what a pity! Your product is rejected. I hope you can produce better products.

Classification of metals is to divide metals into 2 groups of ferrous and ferrous metals according to their properties. The melting point is not very high, so it can be smelted, molded into details of different shapes, easily. ... Some non-ferrous metals have good chemistry, do not rust, are used in the chemical industry. Good thermal and electrical conductivity. Has low mechanical strength. Ferrous metals we use a lot like steel and cast iron, non-ferrous metals like copper, aluminum and bronze. Plastic is widely used in daily life and production, plastic is divided into thermoplastic and thermoset. The classification of metals makes it easy to identify their properties to choose the best use

Hello, I’m Chinh. I am an engineer at AI company. My company is developing a new multipurpose robot called Grakk. It’s shaped rather like a human. The robot is made of aluminum alloy so it only weighs 24 kg and the height is 1.2 m. Grakk has three main components a humanlike body, a processor and sensors. First, its body has two legs  and two arms with joints, knees and wrists which can make the robot move more flexibly and similarly to human, so it can hold things like people. Next, the sensors are installed on the other components to get information. Then, the information from the sensors is used to navigate pathways for the robot or to do something. The processor, the most important part of the robot, is Grakk’s brain. It is used for receiving information from sensors and controlling its body. It is powered by a 53.8 voltage battery and controlled by voice commands. The robot has the ability to do housework, serve meals and talk with people. It only costs 30 millions VND, which is reasonable for Vietnamese people to afford. I like it because it is very useful in modern life. I believe Grakk will be popular in the future.

Hello, my name is Chinh. I am an engineer working at Samsung company. Now, I report on the problems that occurred during this process and the solutions. I am designing a new lathe. It will be completed by the end of April. Currently, I am in the research phase. However, I encountered some problems. There is a difference between drawings 24A and 26A, which shows a contradiction in dimensions for the length of the lathe shaft. The dimensions are correct on the 24A drawing, so I should ignore the opacity of the 26A drawing. I think I have to revise all the drawings to make sure there are no more problems.
