In Figure a sled is held on an inclined plane by a cord pulling directly up the plane. The sled is to be on the verge of moving up the plane. In Fig. 6-34, the magnitude F required of the cord's force on the sled is plotted versus a range of values for the coefficient of static friction ?_s, between sled and plane: F₁= 2.0N, F₂= 5.0N, and ?₂= 0.50. At what angle θ is the plane inclined?
