A uniform horizontal bar of length L = 4 m and weight 265 N is pinned to a vertical wall and supported by a thin wire that makes an angle of theta = 36o with the horizontal. A mass M, with a weight of 329 N, can be moved anywhere along the bar. The wire can withstand a maximum tension of 599 N. What is the maximum possible distance from the wall at which mass M can be placed before the wire breaks?





This one is a little tricky.|||Sum of Moment at base of rode = 0


(265*2)+(329*X)=599*4*(sin36)


530+329X=1408.33


X=2.67 m
