4–66. The force of F = 30 N acts on the bracket as shown.
Determine the moment of the force about the a-a axis of
the pipe if a = 60, b = 60, and g = 45. Also, determine
the coordinate direction angles of F in order to produce the
maximum moment about the a-a axis. What is this moment?

0:47 why is the Moment Ua•(F x r) and not Ua•(r x F)? I was taught that it was always position cross force but is there something in the problem that would make them switch?
