One force acting on a machine part is $\overrightarrow{F} = (-5.00 N)\hat{\imath} + (4.00 N)\hat{\jmath}$. The vector from the origin to the point where the force is applied is $\overrightarrow{r} = (-0.450 m)\hat{\imath} + (0.150 m)\hat{\jmath}$. (a) In a sketch,show $\overrightarrow{r}, \overrightarrow{F},$ and the origin. (b) Use the right-hand rule to determine the direction of the torque. (c) Calculate the vector torque for an axis at the origin produced by this force. Verify that the direction of the torque is the same as you obtained in part (b).
