Question1
A uniform bar is propped against an extremely slick vertical wall. The force of static friction between upper end of the bar and the wall is negligible, but bar remains at rest, in equilibrium. Which statement about bar is wrong?
Question2
A uniform horizontal bar of length L = 4.0 m and weight 120 N is pinned to a vertical wall and supported by a thin wire that makes an angle of θ = 34° with the horizontal. A mass M, with a weight of 330 N, can be moved anywhere all along the bar. The wire can withstand a maximum tension of 573 N. What is the greatest possible distance from the wall at which mass M could be placed before the wire breaks?
