If a loop of chain is spunat high speed, it will roll like a hoop without collapsing. Consider a chain oflinear mass density p thatmu is rollingwithoutslipping at a high speed v_(0) (a) Show that the tension in the chain is F = muv_(0)^(2) (b) If the chain rolls over a small hump, a transverse wave pulse will be generated in the chain. At whatspeedwill it travel alongthe chain ?(c)How far around the loop (in degrees) will a transverse pulse travelin the time the hoop rolls through one complete revolution ? |
