A bar of mass m and length L is balanced on a rough wall as shown. The bar is not attached to the wall in any way (i.e. there is no hinge: the bar is just pushing against the wall). Find: the tension of the cable, and the force of the wall pushing on the bar. Hint: Make your x-axis parallel to the bar. What are the forces from the wall on the bar along those axis?
