The slotted arm OA rotates about a fixed axis through O. At the instant under consideration, θ = 20°, θ˙ = 50 deg/s, and θ¨ = 21 deg/s2. Determine the magnited of the force F applied by arm OA and the magnitude of the force N applied by the sides of the slot to the 0.4-kg slider B. Neglect all friction, and let L = 0.42 m. The motion occurs in a vertical plane
