Homework Equations




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?

Torque and moment are synonymous 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).
