The figure shows a model of a crane that may be mounted on a truck.A rigid uniform horizontal bar of mass m1 = 85.00 kg and length L = 5.600m is supported by two vertical massless strings. String A is attached at a distance d = 2.000m from the left end of the bar and is connected to the top plate. String B is attached to the left end of the bar and is connected to the floor. An object of mass m2 = 3500kg is supported by the crane at a distance x = 5.400m from the left end of the bar. Throughout this problem, positive torque is counterclockwise. Use 9.81kg/m^2 for the magnitude of the acceleration due to gravity.
