"A block is attached to each end of a rope that passes over a pulley suspended from the ceiling. The blocks do not have the same mass. If the rope does not slip on the pulley, then at any instant after the blocks start moving, the rope: "
"A. pulls on both blocks, but exerts a greater force on the heavier block B. pulls on both blocks, but exerts a greater force on the lighter block C...
"A 0.70-kg disk with a rotational inertia given byMR2 /2 is free to rotate on afixed horizontal axis suspended from the ceiling. A string is wrapped around the disk and a 2.0-kg mass hangs from the free end. If the string does not slip, then as the mass falls and the cylinder rotates, the suspension holding the cylinder pulls up on the cylinder with a force of: "

"A 8.0-cm radius disk with a rotational inertia of 0.12kg· m2 is free to rotate on a horizontal axis. A string is fastened to the surface of the disk and a 10-kg mass hangs from the other end. The mass is raised by using a crank to apply a 9.0-N·m torque to the disk. The acceleration of the mass is:"
