One force acting on a machine part is F= (-5.00 N). The vector from the origin to the point where the force is applied is r= (0.333 m)i + (-0.150 m)j + (-0. 450 m). Calculate the magnitude AND direction of the torque for an axis at the origin produced by this force? (The direction is an angle measured counterclockwise from the positive x axis)
