Rod OA rotates counterclockwise at a constant angular rate = 4 rad/s. The double collar B

Rod OA rotates counterclockwise at a constant angular rate θ̇  = 4 rad/s. The double collar B is pin connected together such that one collar slides over the rotating rod and the other collar slides over the circular rod described by the equation r = (1.6 cos θ) m. If both collars have a mass of 0.5 kg, determine the force which the circular rod exerts on one of the collars and the force that OA exerts on the other collar at the instant θ = 45°. Motion is in the horizontal plane.
