Problem 5. The Figure below show two views of a double pulley system (two pulley wheels attached and sharing an axis of rotation) with radii r = 10 cm and R = 30 cm. The pulleys are solid cylinders with mass 0.5 kg and 3.5 kg. A string is wrapped around the large pulley and attached to a mass m of 10 kg. A string is wrapped around the small pulley and attached to a 900 mass M of 20...

The double pulley consists of two parts that are attached to one
another. It has a weight of 49 lb and a centroidal radius of
gyration of kO=0.6ft and is turning with an
angular velocity of 20 rad/s clockwise.
(Figure 1)
Part A
Determine the angular velocity of the pulley at the instant the
20-lb weight moves 2 ft downward.
Express your answer to three significant figures and include the
appropriate units.

A block of mass M = 1.1 kg is attached to a string which is wrapped around a pulley. As the block accelerates due to gravity the pulley rotates clockwise. The pulley can be thought of as a thin cylinder of mass m = 0.5 kg and radius r = 0.26 m. Consider positive to be the block moving down and the pulley rotating clockwise. What is the downwards acceleration of the block? What is the angular acceleration of the...

8. (10 points) Picture taken from problem 19-21. The spool has a weight of 30 lb and a radius of gyration ko=0.45 ft. A cord is wrapped around the spool's inner hub and the end of the chord is subjected to a horizontal force P = 5 lb. Assume the spool rolls and slips. The coefficient of friction between the spool and the ground is uk = 0.1. Determine the spool's angular velocity in 4 s...

3. A gun tackle consits of a light rope and two ideal pulleys. One end of the rope is attached to the ceiling and wrapped around both pulleys, as depicted, while the other end is fastned to mass A. Mass B hangs off the pulley that is free to move. The second pulley is attached to the ceiling. Initially the blocks, which have the same mass, are suspended at the same distance from the ceiling and are subsequently released...
