FRICTION

... FRICTION - the force that present whenever two surfaces are in contact and always acts opposite to the direction of motion. Depends on: • Type of materials in contact • Surfaces of materials ...

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.
