I have three questions left to do and its been very hard because I am out of state with the family and had forgotten to pack my physics book. I really need help on this, I can't find any examples from typing in parts of the question. If you could help me on how to solve this and the equations used, I'd really appreciate it.
1). A uniform horizontal bar of length L = 4.0 m and weight 142 N is pinned to a vertical wall and supported by a thin wire that makes an angle of θ = 27° with the horizontal. See figure 9-52 in the book A mass M, with a weight of 303 N, can be moved anywhere along the bar. The wire can withstand a maximum tension of 570 N. What is the maximum possible distance from the wall at which mass M can be placed before the wire breaks?
2.)A uniform horizontal bar of length L = 4.0 m and weight 142 N is pinned to a vertical wall and supported by a thin wire that makes an angle of θ = 27° with the horizontal. See figure 9-52 in the book A mass M, with a weight of 303 N, can be moved anywhere along the bar. The wire can withstand a maximum tension of 570 N.With M placed at this maximum distance what is the horizontal component of the force exerted on the bar by the pin at A?
3). The third question is similar to the second but asks for vertical component.
