Mechanical engineering is the branch of engineering concerned with the utilisation of the basic laws of mathematics, thermodynamics, heat transfer, fluid dynamics, and system dynamics in order to create unique solutions to physical problems. Mechanical engineering is one of the most diverse engineering disciplines; Mechanical Engineers are often required to create solutions for problems which overlap other specialties such as Civil and Electrical engineering.
In the USA, the primary community for mechanical engineers is the American Society of Mechanical Engineers (ASME), while in the UK it is the Institute of Mechanical Engineers (IMechE).
