lb ft The wheel shown has a weight of 30 lb and a radius of gyration of kg = 0.6 ft. It is attached to a spring which has a stiffness k = 2. and an unstretched length of 1 ft. If the disk is released from rest in the position shown and rolls without slipping, determine its angular velocity at the instant G moves 3 ft to the left. 4 ft Sommi k = 2 lb/ft -3 ft 0.75 ft
The small end rollers of the 6.2-lb uniform slender bar are constrained to move in the slots, which lie in a vertical plane. At the instant when e = 30°, the angular velocity of the bar is 2.6 rad/sec counterclockwise. Determine the angular acceleration of the bar, the reactions at A and B, and the accelerations of points A and B under the action of the 5.1-lb force P. Neglect the friction and mass of the small rollers. The angular acceleration is positive if counterclockwise, negative if clockwise. The acceleration of A is positive if downward, negative if upward. The acceleration of B is positive if down the slot, negative if up the slot. The reaction at A Is positive If to the right, negative If to the left. The reaction at 8 Is positive If up and to the right, negative If down and to the left. L= 5.2 ft 107 P= 5.1 lb Answers: Jad/sec? F = Fg =
19–33. The 80-kg man is holding two dumbbells while standing on a turntable of negligible mass, which turns freely about a vertical axis. When his arms are fully extended, the turntable is rotating with an angular velocity of 0.5 rev/s. Determine the angular velocity of the man when he retracts his arms to the position shown. When his arms are fully extended, approximate each arm as a uniform 6-kg rod having a length of 650 mm, and his body as a 68-kg solid cylinder of 400-mm diameter. With his arms in the retracted position, assume the man is an 80-kg solid cylinder of 450-mm diameter. Each dumbbell consists of two 5-kg spheres of negligible size. -0.20 m 0.65 m 0.3 m H0.3 m Prob. 19–33
The slotted circular disk whose mass is 4.9 kg has a radius of gyration about O of 230 mm. The disk carries the four steel balls, each of mass 0.17 kg and located as shown, and rotates freely about a vertical axis through O with an angular speed of 164 rev/min. Each of the small balls is held in place by a latching device not shown. If the balls are released while the disk is rotating and come to rest relative to the disk at the outer ends of the slots, compute the new angular speed N of the disk. Also find the magnitude |AE| of the energy loss due to the impact of the balls with the ends of the slots. Neglect the diameter of the balls and discuss this approximation. 164 rev/min 145 mm 305 mm
