Mechanical engineering is, in fact, a discipline which uses the fundamental concepts of physics and mathematics to study the motion of objects and the forces that act on them and, thus, seeks to open new windows to technology and industry.

As the most comprehensive branch of engineering, it covers a wide range of disciplines. It covers all sciences and techniques which are related to the energy supply, transformation and consumption; motion generation and transformation; parts and machinery manufacturing and mechanical, thermal, and fluid systems design and control.
