The 4-oz pin B slides along the slot in the rotating arm OC and along the slot DE which is cut in a fixed horizontal plate. Neglecting friction and knowing that arm OC rotates at a constant rate θ0 = 10 rad/s, determine for am given value of θ (a) the radial and transverse components of the resultant force F exerted on pin B, (b) the forces P and Q exerted on pin B by arm OC and the wall of the slot DE, respectively.
