Question

Calculate the tension (in pounds) in the cable.

  • The drawbridge's weight: W = Mg = 7800 lb
  • Its length: ℓ = 33 ft
  • The height the cable reaches: h = 18 ft
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.)
