The pendulum shown below consists of a 100-kg sphere (r= 0.2 m) attached to a 20-kg slender rod OB (L = 2.0 m). It swings about a pin at 0. At the instant 0 = 60°, the pendulum has an angular velocity of oj = 2 rad/s as shown. Determine the angular velocity of the pendulum when 0 = 0° (pendulum is vertical). olso L = 2 m 0 = 60° 20 kg 20 kg 70.4 m 2.2 m -100...

The pendulum shown below consists of a slender rod of length L and a think disk of radius r. If the rope connected to the disk breaks as shown, find the initial angular accleration of pendulum and the reaction forces at O. Assume Wrod = 12 lbs, Wdisk = 20 lbs, r = 2 ft, and L = 3 ft. x = Ox= rad/s 2 (1 decimal) lbs (no decimals) lbs (1 decimal) Oy = 1-1 L
A slender 9 lb rod can rotate in a vertical plane about a pivot at B. A spring of constant k-30 lb/ft and of unstretched length 6 in. is attached to the rod as shown. The rod is released from rest in...
A slender 9 lb rod can rotate in a vertical plane about a pivot at B. A spring of constant k-30 lb/ft and of unstretched length 6 in. is attached to the rod as shown. The rod is released from rest in the position shown. 1) Determine its angular velocity after the rod has rotated through 45.(1 point) 2) Determine the reaction force at pivot point B after the rod rotated through 45. (1 point) 24 in 5 in. 4...

Problem 9 (15 points) A 20-lb slender rod AB is 5 ft long and is pivoted about a point O which is 1 ft from end B. The other end is pressed against a spring of constant k-400 lbin until the spring is compressed 2 in, and the rod is in a horizontal position. If the rod is released from this position, determine its angular velocity and the reaction at the pivot O as the rod passes through a thirty...
