Collinear: means all forces have the same line of action.
Coplanar: lines of actions of all forces are in the same plane.
Concurrent: the lines of actions of all forces pass throu
Biomechanics: the application of classical mechanics on living systems.
Mechanics: study of the effects of forces on bodies. Study includes;
Statics; at rest or equilibrium.
Dynamics; in motion but not at equilibrium.

Steady-state error is the difference between the input and

Stability is the most important system specification.
If a system is unstable, its transient response and
steady-state errors are moot points. An unstable
system cannot be designed for a specific transient
