The figure shows a model of a crane that may be mounted on atruck.A rigid uniform horizontal bar of mass = 80.00 and length = 6.000 is supported by two verticalmassless strings. String A is attached at a distance = 1.900 from the left end of the barand is connected to the top plate. String B is attached to the leftend of the bar and is connected to the floor. An object of mass = 3500 is supported by the crane ata distance = 5.800 from the left end of the bar.
Throughout this problem, positive torque is counterclockwise.Use 9.81 for the magnitude of the accelerationdue to gravity.
Find , the magnitude of the tension in string B.
