Torque is calculated by multiplying the force by the length of the lever arm (in your case, the distance from the capstan barrel axis to the place the force is applied). Thus, let H = the human force applied by one man and let A be the force applied by gravity acting on the anchor. 4 x H x 40" = A x (8"/2 + 1") You can calculate A using F=ma, where the acceleration is that due to gravity. Solve for H. Cheers,
