11. Sir Lost-a-Lot dons his armor and sets out from the castle onhis trusty steed (Fig. P12.11). Usually, the drawbridge is low-ered to a horizontal position so that the end of the bridgerests on the stone ledge. Unfortunately, Lost-a-Lot's squiredidn't lower the drawbridge far enough and stopped it at20.0° above the horizontal. The knight and his horsestop when their combined center of mass is d = 1.00 m fromthe end of the bridge. The uniform bridge is l = 8.00 mlong and has mass 2 000 kg. The lift cable is attached to thebridge 5.00 m from the hinge at the castle end and to apoint on the castle wall h = 12.0 m above the bridge. Lost-a-Lot's mass combined with his armor and steed is 1 000 kg.Determine (a) the tension in the cable and (b) the horizon-tal and (c) the vertical force components acting on thebridge at the hinge.h Problem 11b asks for the x-component of the forceon the bridge due to the hinge.

John is pushing his daughter Rachel in a wheelbarrow when it is stopped by a brick 8.00 cm high (Fig. P12.15). The handles make an angle of = 15.0 with the ground. Due to the weight of Rachel and the wheelbarrow, a downward force of 400 N is exerted at the center of the wheel, which has a radius of 20.0 cm. (a) What force must John apply along the handles to just start the wheel over the brick? (b) What is the force (magnitude and direction) that the brick exerts on the wheel just as the wheel begins to lift over the brick? In both parts, assume the brick remains fixed and does not slide along the ground. Also assume the force applied by John is directed exactly toward the center of the wheel.

A stepladder of negligible weight is constructed as shown in Figure P10.73, with AC = BC = = 4.00 m. A painter of mass m = 70.0 kg stands on the ladder d = 3.00 m from the bottom. Assuming the floor is frictionless, find (a) the tension in the horizontal bar DE connecting the two halves of the ladder, (b) the normal forces at A and B, and (c) the components of the reaction force at the single hinge C that the left half of the ladder exerts on the right half. Suggestion: Treat the ladder as a single object, but also treat each half of the ladder separately.
