A 30-lb slender rod AB is 5 ft long and is pivoted about a point 0 which is 1 ft from end B. The other end is pressed against (NOT connected with) a spring of constant k = 150 lb/ft until the spring is compressed 1 ft. The rod is then in a horizontal position. The mechanism is designed such that no interference occurs during all motions. If the rod is released from rest at this position, when it rotates 45°, determine: a) The angular velocity of rod AB. b) The angular acceleration of rod AB, as well as the magnitude of the reaction force at 0. 5 ft 1ft B

The dynamic system is initially at rest. The rod has a mass of m=0.5kg and a length of L=1m. The CG of the rod is located at G, and the rod is rotated about the point O, a distance, h=0.25m, away from point G. When the rod from above is rotated at the vertical position (swing to 90 degrees counterclockwise), find: a. Angular velocity b. Reaction at O
Please answer this NEATLY, COMPLETELY, and CORRECTLY for an UPVOTE. The mechanism shows two identical 2-kg bars that are 0.15 m long each. They are hinged together at the lower ends and are supported at the upper ends by small rollers of negligible mass which roll on a horizontal rail. Determine the steady state angle θ assumed by the bars when they are accelerating under the action of a constant horizontal force 375.90 Newtons. Also, find the forces on the rollers at A and B as well as the reactions at the hinge C.
