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: e = 36 ft • The height the cable reaches: h = 23 ft
