Question

The flywheel of a motor is connected to the flywheel of an electric generator by a drive belt. The flywheels are of equal size each of radius  . While the flywheels are rotating the tension in the upper and lower portions of the drive belt are     and     respectively. The drive belt exerts a torque       on the generator (around its center). The coefficient of static friction between the drive belt and each flywheel is    . Assume the tension is as high as possible with no slipping between the belt and the flywheel, and that the drive belt is massless.

(a) Derive a differential expression representing the change of tension along the portion of the belt in contact with one of the flywheels. That is find the value of   for one of the two flywheels.

(b) What is    T1,T2

Hil · Answer

I am not sure about (a) I think it is us*d(theta). (b)T/R 1/e^(us*pi)-1 (c)T/R 1/1-e^(-us*pi) I am not 100% positive. Take a look maybe you feel the same way. The tension is opposite.
