The Attempt at a Solution


The book says that the force P causes a torque about the x axis. Why is it not a moment about x?
Why is it specifically a torque in this case?

The terms 'torque' and 'moment' are sometimes used interchangeably, although 'torque' often is used when twisting is involved. Here, the force P causes, at the base of the post support. both a moment about the z axis, Mz, and a moment about the x axis, Mx, where Mz bends the post (a bending moment) and Mx twists the post (a torque).
