A hydraulic crane of total mass (including the mass of the boom) 5300kg supports a load of 800kg. The boom mass 500kg is 7m long and makes an angle of 50 degrees with the horizontal. The boom's center of the boom length. Also assume that the center of mass of the crane excluding the boom acts at the middle of the outrigger jacks that are 4m apart. Draw the FBD of the crane and boom. Find the reaction force at the rear outrigger jack (Nr) and at the front (Nf) for the system to be in equilibrium. Assume the ground is friction less. 7m 7m SO
