1. In a 8"and 3" pulley system, the large wheel turns through 2 rpm. Find the rpm of the smaller wheel.

2. In a 8" and 5" pulley system, the 5" wheel turns through an angle of 30. Find the angle (in degrees) which the 8" wheel turns through.

6. A point on the rim of a wheel of unknown radius in a pulley system has a velocity of 16 . The wheel is making 4 rpms. If the radius of the other wheel is 8 inches, find the 8" wheel's rpms and the unknown wheel's radius.

7. The big wheel of a pulley system turns at 2 rpm and the small wheel turns at 5 rpm. If a point on the rim of the large wheel moves with a speed of 10 , find the radius of each wheel.
