Sir Lost –a- Lot dons his armor and sets out from the castle on his trusty steed in his quest to improve communications between damsels and dragons. Unfortunately his squire lowered the draw bridge too far and finally stopped when it was 20.0º below the horizontal. Lost-a-lot and his horse stop when their combined center of mass is 1.00 m from the end of the bridge. The bridge is 8.00m long and has a mass of 2000 kg. The lift cable is attached to the bridge 5.00 m from the hinge end and to a point on the castle wall 12.00m above the bridge. With his horse and all of his armor the knight in rusty armor has a mass of 1,000 kg. Determine: a) The tension in the cable b) The horizontal force component acting on the bridge at the hinge c) The vertical component at the same point.
