... since the wheel is turning at a constant angular velocity, we can use the equations θ = ωt s = rθ substituting gives us the equation s = r(ωt) and we can calculate the amount of string wrapped around the exterior of the rotor s = (0.025)(1200)(0.105)(10) s = 31.5 meters ...

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.
