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.)...
3. Two uniform cylinders are connected by a belt as shown. Each cylinder weighs W 20 lb and has a radius r= 6 in. Knowing that at the instant shown the angular velocity of cylinder B is 40 rad/s clockwise, determine (a) the distance through which cylinder A will rise before the angular velocity of cylinder B is reduced to 10 rad/s, (b) the tension in the portion of belt connecting the two cylinders.

The 3-lb uniform rod BD is connected to crank AB and to a collar of negligible weight. A couple (not shown) is applied to crank AB causing it to rotate with an angular velocity of 16 rad/s counterclockwise and an angular acceleration of 84 rad/s2 clockwise at the instant shown.

17.7 Disk A, of weight 10 lb and radius r = 6 in., is at rest when it is placed in contact with belt BC, which moves to the right with a constant speed y = 40 ft/s. Knowing that Hex = 0.20 between the disk and the belt, determine the number of revolutions executed by the disk before it attains a constant angular velocity. Fig. P17.7
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.

The 18-lb sphere and 12-lb block (shown in section) are secured
to the arm of negligible mass which rotates in the vertical plane
about a horizontal axis at O. The 7-lb plug is released
from rest at A and falls into the recess in the block when
the arm has reached the horizontal position. An instant before
