Resulting forces, coupling forces?

Question

A piece of plywood in which several holes are being drilled successively has been secured to a workbench by means of two nails. Knowing that the drill exerts a 12 N-m couple on the piece of plywood, determine the magnitude of the resulting forces applied to the nails if they are located
(a) at A and B
(b) at B and C
(c) at A and C

Answer 1

Just divide the torque (12 N-m) by the distance between the two nails that you need the load for, and divide by 2 to get the load on each nail.
