Everything about Applied Mechanics totally explained
Applied mechanics is a branch of the
physical sciences and the practical application of
mechanics. Applied mechanics examines the
response of bodies (solids and fluids) or systems of bodies to external forces. Some examples of
mechanical systems include the flow of a
liquid under
pressure, the fracture of a
solid from an applied
force, or the vibration of an ear in response to
sound. 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 of
engineering, especially
mechanical engineering. In this context, it's commonly referred to as
engineering mechanics. Much of modern engineering mechanics is based on
Isaac 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 sciences, mechanics was said by the American Nobel Prize-winning chemist
Gilbert N. Lewis and the American physical chemist
Merle Randall to be complemented by
thermodynamics, the study of heat and more generally
energy, and
electromechanics, the study of
electricity and
magnetism.
Mechanics in practice
As a scientific discipline, applied mechanics derives many of its principles and methods from the
Physical sciences (in particular,
Mechanics and
Classical Mechanics), from
Mathematics and, increasingly, from
Computer Science. As such, Applied Mechanics shares similar methods, theories, and topics with
Applied Physics,
Applied Mathematics, and
Computational 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 of
seismic waves. Such studies have resulted in disciplines such as
celestial mechanics,
biomechanics and
geomechanics.
A a practical discipline, applied mechanics has also advanced by participating in major inventions throuhout history, such as buildings, ships,
automobiles,
railways,
petroleum refineries,
engines,
airplanes,
nuclear reactors,
composite materials,
computers, and
medical implants. In such connections, the discipline is also known as
Engineering Mechanics, often practiced within
Civil Engineering,
Mechanical Engineering,
Construction Engineering,
Materials Science and Engineering,
Aerospace Engineering,
Chemical Engineering,
Electrical Engineering,
Nuclear Engineering,
Structural engineering and
Bioengineering.
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.
