Question

A Bar Suspended by Two Vertical Strings The figure (Figure 1) shows a model of a crane that may be mounted on a truck. A rigid uniform horizontal bar of mass m1 = 95.0 kg and length L = 5.40 m is supported by two vertical massless strings. String A is attached at a distance d = 1.30 m 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 = 2000 kg is supported by the crane at a distance x = 5.20 m from the left end of the bar. Throughout this problem, positive torque is counterclockwise and use 9.80 m/s^2 for the magnitude of the acceleration due to gravity. Find TA, the tension in string A. Express your answer in newtons using three significant figures. TA = Part B Find TB, the magnitude of the tension in string B. Express your answer in newtons using three significant figures.
