A uniform metal bar of length L and mass M is mounted to an axle that passes through its center of mass as indicated in the figure. The bar is oriented at an angle of 30 degrees to the dotted line as indicated in the figure. A force of magnitude F and pointed to the right is applied to one end of the bar. What is the torque about the axle that is being applied to the bar by the force F? 30° F L Hint: think carefully about angles. O FL O FL OL
