Mechanical engineering explained to kids

Mechanical engineering is the branch of engineering that deals with the design, construction, and operation of machines and tools. It is one of the oldest and broadest of the engineering branches. Mechanical engineers are involved in the design of many different kinds of products, including cars, trucks, bicycles, and aircraft. They also work on power-producing machines such as electric generators, internal combustion engines, and steam and gas turbines. In addition, mechanical engineers design tools that are used in manufacturing, such as lathes and grinding machines. Some mechanical engineers work in the field of biomechanics, which is the study of the mechanical properties of living things. They use their knowledge of mechanics to design devices such as artificial limbs and joints. Other mechanical engineers work in the field of tribology, which is the study of friction and wear. They use their knowledge to design bearings, lubricants, and seals. Mechanical engineering is a very diverse field, and there are many different subfields. Some of the more common subfields are aerospace engineering, automotive engineering, materials engineering, and thermal engineering. Aerospace engineering is the branch of mechanical engineering that deals with the design, construction, and operation of aircraft and spacecraft. Automotive engineering is the branch of mechanical engineering that deals with the design, construction, and operation of cars and trucks. Materials engineering is the branch of mechanical engineering that deals with the properties of materials, such as metals, plastics, and ceramics. Thermal engineering is the branch of mechanical engineering that deals with the transfer of heat. Mechanical engineers use physics and mathematics to solve problems. They use computers to help them design and analyze systems. They also use computers to simulate how these systems will work in the real world. Mechanical engineering is a very important field. It is essential for the design and operation of many different kinds of products and systems.
