Mechanical engineering is a discipline ofengineeringthat applies the principles of

engineering,physicsandmaterials sciencefor analysis, design,manufacturing, and

maintenance ofmechanicalsystems. It is the branch of engineering that involves the

production and usage ofheatand mechanical power for the design, production, and

operation ofmachinesandtools.[1]It is one of the oldest and broadestengineering

disciplines.

The engineering field requires an understanding of core concepts

includingmechanics,kinematics,thermodynamics,materials science,structural

analysis, andelectricity. Mechanical engineers use these core principles along with

tools likecomputer-aided engineering, andproduct lifecycle managementto design

and analyzemanufacturing plants, industrial equipment and machinery,heating and

cooling systems,transportsystems,aircraft,watercraft,robotics,medical

devices,weapons, and others.

Mechanical engineering emerged as a field during theindustrial revolutionin Europein the 18th century; however, its development can be traced back several thousand

years around the world. Mechanical engineering science emerged in the 19th century

as a result of developments in the field ofphysics. The field has continually evolved

to incorporate advancements in technology, and mechanical engineers today are

pursuing developments in such fields ascomposites,mechatronics,

andnanotechnology. Mechanical engineering overlaps withaerospace

engineering,metallurgical engineering,civil engineering,electrical

engineering,petroleum engineering,manufacturing engineering,chemical engineering,

and other engineering disciplines to varying amounts. Mechanical engineers may also

work in the field ofBiomedical engineering, specifically withbiomechanics,transport

phenomena,biomechatronics,bionanotechnologyand modeling of biological systems,

like soft tissue mechanics.
