Q4: The pinion A of the hoist motor drives gear B which is attached to the hoisting drum. The load L is lifted from its rest position and acquires an upward velocity of (1m/sec) in a vertical rise of (1.5 m) with constant acceleration. As the load passes this position, compute (a) the acceleration of point C on the cable in contact with the drum and (b) the angular velocity and angular acceleration of the pinion A. See figure (4)

The load L is lowered by the two pulleys which are fastened together and rotate as a single unit. For the instant represented, drum A has a counterclockwise angular velocity of 4 rad/sec which is decreasing by 4 rad/sec each second. Simultaneously, drum B has a clockwise angular velocity of 6 rad/sec, which is increasing by 2 rad/sec each second.

Current Attempt in Progress The gear train shown operates in a horizontal plane and is used to transmit motion to the rack D of mass mp = 5.1 kg. If an input torque M = 60 Nom is applied to gear A, what will be the magnitude of the resulting acceleration a of the unloaded rack? (The mechanism which it normally drives has been disengaged.) Gear C is keyed to the same shaft as gear B. Gears A, B, and C have pitch diameters dÃ = 175 mm, dB = 305 mm, and dc = 175 mm, and centroidal mass moments of inertia l = 0.49 kg•m², lg = 2.87 kg•m², and lc = 0.49 kg•m², respectively. All friction is negligible. Answer a = i D m/s²
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 =
