The four-bar mechanism lies in a vertical plane and is controlled by crank OA which rotates counterclockwise at a steady rate of 60 rev /min. a) Determine the torque M which must be applied to the crank at O when the crank angle = 30°. The uniform coupler AB has a mass of 7 kg, and the masses of crank OA and the output arm BC may be neglected.
