determine the magnitude of the normal force which the curved rod exerts on one collar at the instant θ=110°

Rod O A rotates counterclockwise with a constant angular velocity of θ=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-cosθ) ft. (Figure 1)Part AIf both collars weigh 0.80 lb, determine the magnitude of the normal force which the curved rod exerts on one collar at the instant θ=110° . Neglect...
