Mechanical engineering is a branch of engineering that applies the principles of Mechanics and Materials science for analysis, design, manufacturing, and maintenance of mechanical systems. It involves the production and usage of heat and mechanical power for the design, production, and operation of machines and tools. They can range from building a rocket ship down to things as …

Torque converter, opened, interior similar to a retarder. A retarder is a device used to augment or replace some of the functions of primary friction -based braking systems, usually on heavy vehicles. Retarders serve to slow vehicles, or maintain a steady speed while traveling down a hill, and help prevent the vehicle from "running away" by ...

Engineering is the use of scientific principles to design and build machines, structures, and other items, including bridges, tunnels, roads, vehicles, and buildings. The discipline of engineering encompasses a broad range of more specialized fields of engineering, each with a more specific emphasis on particular areas of applied mathematics, applied science, and types of application.

The mechanical engineering (also known as mechanical engineering called) is a classic engineering science and extends to development, design and manufacture of machines. These include. Power machines ( steam engine , motor or turbine ), Working machines ( blower , pump or compressor ), Machine tools ( turning , milling or grinding machine ...
