... b) A flywheel with a moment of inertia I = 5 kg m2 is mounted on a light axle. It is initially stationary. A torque of 100 N m is applied to the axle for 100 s. (i) Calculate the final angular velocity of the flywheel. v = u + at = u + F/m t, so f = I + t = 0 + /I t = 2000 rads–1. (ii) Calculate ...

Simple Harmonic Motion
... Cycle: One complete oscillation of the body. Period (T): The time (in s) for one complete cycle. Frequency (f): The number of complete cycles made per second (in Hertz or s-1). (Note: f = 1 / T) Angular frequency (ω): Also called angular speed, in circular motion this is a measure of the rate of rot ...

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.
