- Applied mechanics
**Applied mechanics**is a branch of thephysical science s and the practical application ofmechanics . Applied mechanics examines the "response of bodies (solids and fluids) or systems of bodies to externalforce s". Some examples of "mechanical systems" include the flow of aliquid underpressure , the fracture of asolid from an appliedforce , or the vibration of an ear in response tosound . A practitioner of the discipline is known as a.mechanician Applied mechanics, as its name suggests, bridges the gap between physical theory and its application to

technology . As such, applied mechanics is used in many fields ofengineering , especiallymechanical engineering . In this context, it is commonly referred to as**engineering mechanics**. Much of modern engineering mechanics is based onIsaac Newton 's laws of motion while the modern practice of their application can be traced back to Timoshenko, who is said to be the father of modern engineering mechanics.Within the theoretical sciences, applied mechanics is useful in formulating new ideas and theories, discovering and interpreting phenomena, and developing experimental and computational tools. In the application of the

natural science s, mechanics was said by the American Nobel Prize-winning chemistGilbert N. Lewis and the American physical chemistMerle Randall to be complemented bythermodynamics , the study of heat and more generallyenergy , andelectromechanics , the study ofelectricity andmagnetism . [*"Thermodynamics - and the Free Energy of Chemical Substances". Lewis, G. and M. Randall (1923)*]**Mechanics in practice****As a scientific discipline**, applied mechanics derives many of its principles and methods from thePhysical sciences (in particular,Mechanics andClassical Mechanics ), fromMathematics and, increasingly, fromComputer Science . As such, Applied Mechanics shares similar methods, theories, and topics withApplied Physics ,Applied Mathematics , andComputational Science .**As an enabling discipline**, applied mechanics has received impetus from the study of natural phenomena such as orbits of planets, circulation of blood, locomotion of animals, crawling of cells, formation of mountains, and propagation ofseismic waves . Such studies have resulted in disciplines such ascelestial mechanics ,biomechanics andgeomechanics .**As a practical discipline**, applied mechanics has also advanced by participating in major inventions throughout history, such as buildings, ships,automobiles ,railways ,petroleum refineries ,engines ,airplanes ,nuclear reactors ,composite materials ,computers , andmedical implants . In such connections, the discipline is also known as "Engineering Mechanics", often practiced withinCivil Engineering ,Mechanical Engineering ,Construction Engineering ,Materials Science and Engineering ,Aerospace Engineering ,Chemical Engineering ,Electrical Engineering ,Nuclear Engineering ,Structural engineering andBioengineering .**Applied mechanics in engineering**Typically, engineering mechanics is used to analyze and predict the acceleration and deformation (both elastic and plastic) of objects under known

**forces**(also called**loads**) or stresses.When treated as an area of study within a larger engineering curriculum, engineering mechanics can be subdivided into

*, the study of non-moving bodies under known loadsStatics

***Dynamics**(or**kinetics**), the study of how forces affect moving bodies

*orMechanics of materials , the study of how differentstrength of materials materials deform under various types of stress

***Deformation mechanics**, the study of deformations typically in the elastic range

*, the study of how fluids react to forces. Note that fluid mechanics can be further split intoFluid Mechanics **fluid statics**and**fluid dynamics**, and is itself a subdiscipline of**continuum mechanics**. The application of fluid mechanics in engineering is called.hydraulics

*is a method of applying mechanics that assumes that all objects are continuous. It is contrasted byContinuum mechanics **mechanics**and thefinite element method .**Major topics of applied mechanics**
