Answer 2

Applied and reaction moment sign conventions follow the right hand rule (RHR-Figure 2). ... A moment applied to the body is positive if it tries to turn the body in a counter-clockwise direction and negative if it tries to turn the body in a clockwise direction. It's just the opposite looking out of the x-y plane!
