This is a drawbridge, held in place by a cable. The hinge is frictionless. This problem and the next two involving this situation use American units: weight and other forces are in pounds, and torque is in pound-feet. Calculate the torque (positive number) on the drawbridge due to its weight, in Ib'ft. (Use the hinge as your axis.) h hinge 3l/4 • The drawbridge's weight: W = Mg = 4300 lb • Its length: € = 36 ft • The height the cable reaches: h = 23 ft

When reducing the mass of a racing bike, the greatest benefit is realized from reducing the mass of the tires and wheel rims. Why does this allow a racer to achieve greater accelerations than would an identical reduction in the mass of the bicycle’s frame?
An automobile engine can produce 200Nm of torque. Calculate the angular acceleration produced if 95.0 of this torque is applied to the drive shaft, axle, and rear wheels of a car, given the following information. The car is suspended so that the wheels can turn freely. Each wheel acts like a 15.0-kg disk that has a 0.180-m radius. The walls of each tire act like a 2.00-kg annular ring that has inside radius of 0.180 m and outside radius of 0.320 m. The tread of each tire acts like a 10.0-kg hoop of radius 0.330 m. The 14.0-kg axle acts like a rod that has a 2.00-cm radius. The 30.0-kg drive shaft acts like a rod that has a 3.20-cm radius.
