Question

PROBLEM, DUE 11/27/2018 IN CLASS Consider a real pulley. Unlike the pulley we used previously in class, in a real pulley there is friction between the pulley and its axle, and rotational inertia that must be taken into account. axle R 30cm Fr 18N Thr 1.1Nm frictional torque w 30 rad/sec t 3sec m 4kg FT Given the above parameters, find the value of the moment of inertia of the pulley. Assume the axle is small enough that the pulley behaves as a disc.
