Class Notes
... An object in equilibrium has no acceleration because the forces on it are balanced. According to Newton's 1st law, this means that the object is “not moving” or is moving at constant velocity. When 3 or more concurrent forces are in equilibrium they form a closed triangle or polygon when drawn t ...

Hunting oscillation
Hunting oscillation is a self-oscillation, usually unwanted, about an equilibrium. The expression came into use in the 19th century and describes how a system ""hunts"" for equilibrium. The expression is used to describe phenomena in such diverse fields as electronics, aviation, biology, and railway engineering.
