B7. A uniform bar of mass m= 25.0kg and length L= 4m is attached to a vertical wall at a point about which it can rotate. The other end of the bar is supported by a massless string at an angle 8 = 400. (a) Draw an extended free-body diagram for the bar. (b) What is the maximum distance from the wall (1) that a mass M = 60 kg can be supported on the bar if the maximum tension the string can maintain without breaking is 500N? (c) If the angle (8) is decreased (no other change), will your answer to Part (b) increase or decrease? Explain.e b)
