The pendulum consists of a 12-kg uniform disk and a 3-kg uniform slender rod. It is released from rest in the position shown. Suppose that L = 2.5 m 08 m *M= 30N - m L. Part A Determine its angular velocity, measured clockwise, when it rotates clockwise 90°. Express your answer using three significant figures. Enter positive value if the angular velocity is clockwise and negative value if the angular velocity is counterclockwise. ANSWER: rad/s %3=

The motor turns gear A with a constant angular acceleration, a = 4 rad/s², starting from rest. TA=71, rB=230, rp=121 The cord is wrapped around pulley D which is rigidly attached to gear B. LA TA rB "D з тав Find the distance of cylinder C in mm that it travels it t=2.4 sec. Give your answer as an integer.

4. 4) The hydraulic cylinder Dextends, moves the rigid rod ABC, and causes the collar A to move with velocity and acceleration both to the left. If the dimensions/₁ 1.0 ft, and /2 = 2.0 ft, vµ = 5.5 ft/s, aµ = 2.1 ft/s², and the angle 0 = 30°, determine the angular acceleration (in rad/s²) of rod ABC. Negative sign must be included if the angular acceleration is clockwise. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point. Your Answer: 1₁ Answer B 12 ÏÏ a =
