A uniform horizontal bar of length L = 4.0 m and weight 100 N is pinned to a vertical wall and supported by a thin wire that makes an angle of theta = 37 degrees with horizontal. A mass M, with a weight of 343 N, can be moved anywhere along the bar. The wire can withstand a maximum tension of 552 N.
a) What is the maximum possible distance from the wall at which mass M can be placed before the wire breaks?
b) With M placed at this maximum distance what is the horizontal component of the force exerted on the bar by the pin at A?
c) With M placed at this maximum distance what is the vertical component of the force exerted on the bar by the pin at A?
