A 2-kg small block B fits inside a smooth slot cut in arm OA. The arm rotates counterclockwise in a vertical plane at a constant rate of 5 rad/s and r = 0.5 – 0.3 cos 0 in meters. At the instant that 0= 30°, determine (a) the force exerted by the spring on block B, (b) the normal force exerted by the arm OA on block B. Use radial and transverse components.
