Sir Lost-a-Lot dons his armor and sets out from the castle on his trusty steed (see figure below). Usually, the drawbridge is lowed 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 it at 8 20.0° above the horizontal. The knight and his horse stop when their combined center of mass is d = 1.00 m from the end of the bridge. The uniform bridge is = 7.50 m long and has a mass of 1 800 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, Lost-a-Lot's mass combined with his armor and steed is 900 kg. (a) Determine the tension in the cable. N (b) Determine the horizontal force component acting on the bridge at the hinge. magnitude N direction Select (c) Determine the vertical force component acting on the bridge at the hinge. magnitude magnitude direction -Select-v N
