Analyze problems to see how mechanical and thermal devices might help solve the problem. Design or redesign mechanical and thermal devices using analysis and computer-aided design. Develop and test prototypes of devices they design. Analyze the test results and change the design as needed. Oversee the manufacturing process for the device.
Mechanics (Greek: Μηχανικά; Latin: Mechanica), also called Mechanical Problems or Questions of Mechanics, is a text traditionally attributed to Aristotle, but generally regarded as spurious (cf. Pseudo-Aristotle). [1]
The goal of mechanical theory is to solve mechanical problems, such as arise in physics and engineering. Starting from a physical system—such as a mechanism or a star system—a mathematical model is developed in the form of a differential equation. The model can be solved numerically or analytically to determine the motion of the system.
[3] [4] In 1882, Hertz solved the contact problem of two elastic bodies with curved surfaces. This still-relevant classical solution provides a foundation for modern problems in contact mechanics. For example, in mechanical engineering and tribology, Hertzian contact stress is a description of the stress within mating parts. The Hertzian ...
GOBankingRates got in touch with some automotive experts to find out what the four most expensive mechanical problems plaguing used cars are — with number one being the most expensive. Here is ...
Virtual work is the total work done by the applied forces and the inertial forces of a mechanical system as it moves through a set of virtual displacements. When considering forces applied to a body in static equilibrium, the principle of least action requires the virtual work of these forces to be zero.
Heat engine – a system that converts heat or thermal energy—and chemical energy—to mechanical energy, which can then be used to do mechanical work.
