QUESTION:

13-89. Rod OA rotates counterclockwise with a constant angular velocity of 0 =5 rad/s. The double collar B is pin-connected together such that one collar slides over the rotating rod and the other slides over the horizontal curved rod. of which the shape is described by the equation r = 1.5(2 - cos 0) ft. If both collars weigh 0.75 lb. determine the normal force which the curved rod exerts on one collar at the instant 0 = 120. Neglect friction.

ANSWER:

Problem 13-89

Rod OA rotates counterclockwise with a constant angular velocity of 0 =5 rad/s. The double collar B is pin-connected together such that one collar slides over the rotating rod and the other slides over the horizontal curved rod. of which the shape is described by the equation r = 1.5(2 - cos 0) ft. If both collars weigh 0.75 lb. determine the normal force which the curved rod exerts on one collar at the instant 0 = 120. Neglect friction.
