... A lorry is travelling a constant speed of 60 mph. If friction between the tyres and the road can be ignored at this speed, and internal losses such has heating etc can be ignored, the driving force of the engine is balanced by air resistance. If the cab has a cross section of 8 m2, estimate the engi ...

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.
