A lever like that shown in Figure 5.13(b) is used to press a cap on a container. To press on the cap, 10 lb of force is required at the handle [(F1 in Figure 5.13b)] with a stroke of 2 in. The total length of the lever is 18 in., and the distance from F2 to the pivot is 3 in. Find the force and stroke that results at F2.
