Sir Lost-a-Lot dons his armor and sets out from the castle on his trusty steed (Fig. P12.11). Usually, the drawbridge is low- ered to a horizontal position so that the end of the bridge rests on the stone ledge. Unfortunately, Lost-a-Lot's squire didn't lower the drawbridge far enough and stopped 1it at 0 = 20.0° above the horizontal. The knight and his holse stop when their combined center of mass is d = 1.00 m from 8.00 m %3D the end of the bridge. The uniform bridge is l = long and has mass 2 000 kg. The lift cable is attached to the bridge 5.00 m from the hinge at the castle end and to a point on the castle wall h = 12.0 m above the bridge. Losts Lot's mass combined with his armor and steed is 1 000 5 %3D %3D Determine (a) the tension in the cable and (b) the horizon- al and (c) the vertical force components acting on pridge at the hinge.
