The figure (Figure 1) shows a model of a crane that may be mounted on a truck.A rigid uniform horizontal bar of mass m1m1m_1 = 90.0 kgkg and length LLL = 5.20 mm is supported by two vertical massless strings. String A is attached at a distance ddd = 1.20 mm 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 m2m2m_2 = 3500 kgkg is supported by the crane at a distance xxx = 5.00 mm from the left end of the bar. Throughout this problem, positive torque is counterclockwise and use 9.80 m/s2m/s2 for the magnitude of the acceleration due to gravity. Find TA, the tension in string A. Find TB, the magnitude of the tension in string B.
