Mechanics is, inwards the nearly full general sense, the written report of forces in addition to their upshot upon matter. Typically, technology scientific discipline mechanics is used to analyze in addition to predict the acceleration in addition to deformation (both elastic in addition to plastic) of objects nether known forces (also called loads) or stresses. Subdisciplines of mechanics include
- Statics, the written report of non-moving bodies nether known loads, how forces touching on static bodies
- Dynamics (or kinetics), the written report of how forces touching on moving bodies
- Mechanics of materials, the written report of how dissimilar materials deform nether diverse types of stress
- Fluid mechanics, the written report of how fluids react to forces[23]
- Kinematics, the written report of the motion of bodies (objects) in addition to systems (groups of objects), spell ignoring the forces that crusade the motion. Kinematics is oftentimes used inwards the pattern in addition to analysis of mechanisms.
- Continuum mechanics, a method of applying mechanics that assumes that objects are continuous (rather than discrete)

Mechanical engineers typically role mechanics inwards the pattern or analysis phases of engineering. If the technology scientific discipline projection were the pattern of a vehicle, statics mightiness live employed to pattern the frame of the vehicle, inwards social club to evaluate where the stresses volition live nearly intense. Dynamics mightiness live used when designing the car's engine, to evaluate the forces inwards the pistons in addition to cams every bit the engine cycles. Mechanics of materials mightiness live used to select appropriate materials for the frame in addition to engine. Fluid mechanics mightiness live used to pattern a ventilation organization for the vehicle (see HVAC), or to pattern the intake organization for the engine.
