In Fig. 6-23, 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- 28, the magnitude F required of the cords force on the sled is plotted versus a range of values for the coefficient of static friction ms between sled and plane: F1 " 2.0 N, F2 " 5.0 N, and m2 " 0.50.At what angle u is the plane inclined?
