mechanics

The branch of physics that is concerned with the analysis of the action of forces on matter or material systems.

Design, construction, and use of machinery or mechanical structures.

The functional and technical aspects of an activity.

The science which explains natural phenomena by depicting them with mathematical precision as dependent solely upon relations of motion.

The theory of machines.

The mathematical doctrine of the motions and tendencies to motion of particles and systems under the influence of forces and constraints; in a narrower sense, this doctrine as applied to systems of rigid bodies.

That science, or branch of applied mathematics, which treats of the action of forces on bodies.

that portion of physiology which has for its object the investigation of the laws of equilibrium and motion in the animal body. The most important mechanical principle is that of the lever, the bones forming the arms of the levers, the contractile muscles the power, the joints the fulcra or points of support, while the weight of the body or of the individual limbs constitutes the weight or resistance.

the principles of abstract mechanics applied to human art; also, the practical application of the laws of matter and motion to the construction of machines and structures of all kinds.

the principles governing the motion of bodies in orbit around other bodies under gravitational influence, such as artificial Earth satellites.
