Lever a fixed point. The lever operates by applying forces at different distances from the fulcrum, or a pivot. Assuming the lever does not dissipate or store energy, the power into the lever must equal the power out of the lever. As the lever rotates around the fulcrum, points farther from this pivot move faster than points closer to the pivot. Therefore, a force applied to a point farther from the pivot must be less than the force located at a point closer in, because power is the product of force and velocity. If "a" and "b" are distances from the
Lever action for shooting off hand from a standing position to some shooters. There are, however, some lever-action rifles—such as the Winchester Model 1895, which saw service with the Russian Army in World War I—that use a box magazine.<br> Many newer lever-action rifles are capable of shooting groups smaller than 1 minute of angle, making them equal to the accuracy of most modern bolt-action rifles. Another explanation for the lack of widespread use of lever action designs stems from the initial inability to fire high-pressure cartridges. Safe operation could only be carried out by using low-pressure cartridges in the toggle-lock lever action
