The frame assembly has a mass of 8000 kg and it is hoisted using the boom and pulley system shown in the picture. The boom has a mass of 2000 kg and a mass center at G. a) Determine the compressive force in the hydraulic cylinder needed to support the boom when the frame assembly is off the ground but the actual lifting hasn’t started yet. b) Lifting starts: the winch at B draws in the cable with an acceleration of 2 m/s 2 . Determine the compressive force of the cylinder now.
