Solve using impulse moment of rigid bodies: angular momentum Problem 2 The carriage C (W-Ξ 8 lb) is supported as shown by two uniform disks (WAWB 2 lb), each having a radius rA TB 2.5 in. The carriage is initially at rest. Assume that the disks roll without sliding. Determine the velocity of the carriage t 3 s after the P 1.2 lb force has been applied.

A 520 lb uniform disk with center G and radius r = 3 ft is connected by a pulley system to a counterweight A weighing 75 lb. The system is initially at rest when A is allowed to drop, thus causing the disk to roll without slipping to the right. Neglect the inertia of pulley B and the cord, but model pulley C as a uniform disk with radius rC = 0.8 ft and weight WC = 50 lb. Assume...
A 5-lb bar is attached to a 10-b uniform cylinder by a square pin, P, as shown. Knowing that r= 16 in., h= 8 in., 0 = 20°, L = 20 in, and w = 2 rad/s at the instant shown, determine the reactions at Pat this instant assuming that the cylinder rolls without sliding down the incline.

Two uniform cylinders, each of weight W= 10 lb and radius r = 5 in., are connected by a belt as shown. Knowing that at the instant shown the angular velocity of cylinder B is 28 rad/s clockwise, determine the distance through which cylinder A will rise before the angular velocity of cylinder B is reduced to 5 rad/s and the tension in the portion of the belt connecting the two cylinders. (Round the final answers to two decimal places.)...
Prob. A 20-b uniform disk is placed in contact with an inclined surface and a constant 7.5 lb-ft couple M is applied as shown. The weight of the link AB is negligible. Knowing that the coefficient of kinetic friction at D is 0.4, determine (a) the angular acceleration of the disk, (b) the force in the link AB. a rough horizontal surface and end B supported by a smooth vertical surface. Knowing that the deceleration of the truck is 12...

1. The ends of a uniform bar AB with length l= 36.0 in and weight W = 30.0 lb are attached to collars of negligible weight that slide without friction along fixed bars. A vertical force P is applied to collar B. The bar is initially at rest in the position shown and the initial angular acceleration of A is 40.0 ft/s to the left, aA = – 40 ft/s i. o= 30° {= 36 in O Draw a free...
The Geneva mechanism shown is used to provide an intermittent rotary motion of disk S. Disk D weighs 2 lb and has a radius of gyration of 0.9 in. and disk S weighs 6 lb and has a radius of gyration of 1.5 in. The motion of the system is controlled by a couple M applied to disk D. A pin Pis attached to disk D and can slide in one of the six equally spaced slots cut in disk...
2) A uniform solid ball has a mass of 20 g and a radius of 5 cm. It rests on a horizontal surface. A sharp force is applied to the ball in the horizontal direction 9 cm above the surface. The force rises linearly from 0 to a peak value of 40,000 N in 10-4 s and then decreases linearly to in another 10-4 s. (The moment of inertia for a solid ball ismR2) a) What is the velocity of...
