A) M, a solid cylinder (M=1.67 kg, R=0.127 m) pivots on a thin, fixed, frictionless bearing. A string wrapped around the cylinder pulls downward with a force F which equals the weight of a 0.730 kg mass, i.e., F = 7.161 N. Calculate the angular acceleration of the cylinder.

B) If instead of the force F an actual mass m = 0.730 kg is hung from the string, find the angular acceleration of the cylinder.

C) How far does m travel downward between 0.690 s and 0.890 s after the motion begins?

D) The cylinder is changed to one with the same mass and radius, but a different moment of inertia. Starting from rest, the mass now moves a distance 0.337 m in a time of 0.450 s. Find Icm of the new cylinder.

A solid cylinder has a mass of 100 kg and radius 0.225m. The cylinder is attached to a frictionless horizontal axle. A long (light weight) cable is wrapped around the cylinder. Attached to the end of the cable is a 1.50 kg mass. The system is initially stationary. The hanging mass is then released. The mass pulls on the cable as it falls and this causes the cylinder to rotate. a) What is the velocity of the hanging mass after...

A solid uniform disk of mass M = 9.6 kg and radius R = 21 cm rests with its flat surface on a frictionless table (i.e., the axis of the cylinder is perpendicular to the table.) The diagram shows a top view. A string is wrapped around the rim of the disk and a constant force of F = 10.8 N is applied to the string. The string does not slip on the rim. 1) What is the acceleration of...
