The mechanism below has a crank that revolves clockwise at O. B 1.2 kg 200 mm 60 mm 30° O 50 rad/s Using vector diagrams, determine: a. The linear velocity of the piston and the angular velocity of the link AB about A. b. The angular acceleration of the link AB about A and the inertial resistance produced by the piston. c. Using trigonometry, confirm your results for the velocity in parts (a)
