2. A uniform horizontal lever of length 4.33 m is pivoted at its mid-point. A vertically downward force of 2.71 N is acting at the right end of the lever. An unknown vertically downward force is acting at a distance of 0.13 m to the left of the pivot. If the lever is in equilibrium, calculate the force exerted by the pivot (fulcrum) on the lever.
