Problem: A wheel consists of a disk of outer radius R = 1.6 m, with a concentric axle of inner radius r = 0.48 m. The wheel is pulled by a rope looped around the axle. The total mass of the wheel (disk + axle) is M = 12.0 kg and its moment of inertia is I = 18.4 kg m/s. A constant force F = 110 N applied horizontally at the circumference of the axle, causes the wheel to...

A freely spinning wheel of mass M and radius R and moment of inertia I has...
A freely spinning wheel of mass M and radius R and moment of inertia I has its center attached to a fixed point a distance H above the ground. A thin thread is wrapped around the edge of the wheel, and connected to a mass, M (same as the wheel). When the mass is released from rest, it falls the distance H in a time delta t. In terms of M, g, I and H, how much time, delta t,...
