Hi ronaldo

How are you ?

I am sophomore at hanoi university of industry . My major is mechanical engineering technology. Mechanical Engineering is a full-time course and lasts for 4 years . After graduation I will get a Bachelor’s Degree in Mechanical Engineering Technology. I’m having 4 subjects this semester: physics Engineering Drawing, Industrial Machines, and CAD. English is very hard with me because learning english you have to remember a lot of word . At univercity, I enjoy studying physics because it help my logical thinking better . I have 6 classes a week and my class at 7.00 am and finishes at 12.00 everyday. I usually spend 2 hours studying by myself. I think I need time management skills ,note taking skills and presentation skills . i like studying at my university .

I'm waiting for your news.

See you

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.

Metals can be classified based on their physical and chemical properties, including ductility, malleability, and conductivity. According to the diagram, the engineering materials can be classified into two main types: metals and non metal. Ferrous metals contain iron and are magnetic, while non-ferrous metals do not contain iron and are not magnetic . the most commonly used materials are metals. There are two types of metals: ferrous metal and non-ferrous metal. Ferrous metal has cast iron and steel. Non-ferrous metal includes copper ,bronze and aluminum. Non metal is divided into two categories, ceramics and plastics. Plastic is divided into two types, thermoplastic and thermoset .that’s all

Hello, I’m trieu . I am an engineer at Samsung company. My company is developing a new robot named Blue. 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. Blue 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 humans, so it can hold

I’m Trieu . I had a frustrating experience with my chainsaw while cutting trees in my garden. Suddenly, the chain came off, and I didn't have the right tools to fix it. I had to stop working and look for a nearby hardware store to purchase what I needed. Once I had the tools, I managed to fix the chain and continue my work. However, I realized the importance of being more prepared for such situations in the future. I plan to bring the necessary tools and educate myself more about fixing common problems with the machine to prevent further disruptions.that’s all

I'm a mechanical engineering major at university. After careful consideration, I have decided that becoming a mechanical engineer is my ideal profession. As a mechanical engineer, there are many career options available, such as product design and development, research and development of new technologies, overseeing production and quality control, providing customer consultation and support, and maintaining and repairing mechanical systems. To be a successful mechanical engineer, one needs to have specialized knowledge and skills, creative thinking abilities, practical communication skills, a sense of responsibility, and the ability to continue learning. I have chosen this career path because I believe it is well-suited to my skills and that I can grow and develop within this field in the future.
