Chapter 18, Problem 6P
A force of P = 20 N is applied to the cable, which causes the 175-kg reel to turn without slipping on the two rollers A and B of the dispenser. Determine the angular velocity of the reel after it has made two revolutions starting from rest. Neglect the mass of the cable. Each roller can be considered as an 18-kg cylinder, having a radius of 0.1 m. The radius of gyration of the reel about its center axis is kG = 0.42 m.

A force of P = 60 N is applied to the cable, which causes
the 200-kg reel to turn since it is resting on the two rollers
A and B of the dispenser. Determine the angular velocity of
the reel after it has made two revolutions starting from rest.
Neglect the mass of the rollers and the mass of the cable.
Assume the radius of gyration of the reel about its center
axis remains constant at k, = 0.6 m.
The 31-kg reel is mounted on the 16-kg cart.
Part A: If the cable wrapped around the inner hub of the reel is subjected to a force of P=50N, determine the velocity of the cart when t = 4.2 s. The radius of gyration of the reel about its center of mass O is kO=250mm. Neglect the size of the small wheels.
Part B: Determine the angular velocity of the reel when t = 4.2 s.
The frame of the tandem drum roller has a weight of
4025 lb, excluding the two rollers. Each roller has a
weight of 1610 lb and a radius of gyration about its
center of 1.2 ft. For a short time, starting from rest, a
torque of M = 300 lb ft is supplied to the rear roller.
Determine the speed of the drum roller after it
has moved forward 30 ft.
Determine the time it took to travel the 30 ft.
