Two metal disks, one with radius R1 = 2.50 cm and mass M1 = 0.800 kg and the other with radius R2 = 5.10 cm and mass M2 = 1.70 kg
Two metal disks, one with radius R1 = 2.50 cm and mass M1 = 0.800 kg and the other with radius R2 = 5.10 cm and mass M2 = 1.70 kg, are welded together and mounted on a frictionless axis through their common center (Figure 1).
Part A
What is the total moment of inertia of the two disks?
Part B
A light string is wrapped around the edge of the smaller disk, and a 1.50 kg block is suspended from the free end of the string. If the block is released from rest at a distance of 1.20 m above the floor, what is its speed just before it strikes the floor?

A mass m1 = 5.20 kg and a mass m2 = 2.50 kg are suspended by a pulley that has a radius of 8.00 cm and a mass of 2.70 kg (see figure). The cord has a negligible mass and causes the pulley to rotate without slipping. The pulley rotates without friction. Treating the pulley as a uniform disk, determine the tension in the right cord.

An Atwood's machine has one block of m1 = 0.150 kg and the other is of m2 = 0.210 kg. The disk pulley, which is mounted in horizontal, frictionless bearings, has a radius of 5.0 cm. When released from rest, the heavier block is observed to fall Δy = 80.0 cm in 4.0 sec. The moment of inertia for the pulley is: kg m2.
