Flywheel angular momentum
WebFLYWHEEL It may be noticed that if the frictional torque, f, is constant, then the angular acceleration of the system, 1, is also constant.With this assumption 1 may be measured experimentally; if t1 is the time taken for the string to unwind N1 turns from the axle (i.e. the time taken for the mass M to drop off the axle), then the flywheel will have rotated …

WebOct 5, 2011 · Bearings – alloy bearings proved to wear out quite rapidly, at first reducing efficiency and later rendering the flywheel useless; Gyrobuses required constant service because of this; Angular momentum – the momentum stored in the flywheel will act against direction changes, which in transport can make turns a complex task. WebMar 16, 2013 · As an aside, in researching angular momentum and bicycle dynamics, I was surprised to find that angular momentum is not primarily responsible for the stability of a moving bicycle. Apparently, someone has constructed a bicycle with a counter-rotating flywheel to cancel the angular momentum of the spinning wheels, and the bicycle was …
