Lever a place to stand, and I shall move the Earth with it' is a remark of Archimedes who formally stated the correct mathematical principle of levers (quoted by Pappus of Alexandria). It is assumed that in ancient Egypt, constructors used the lever to move and uplift obelisks weighing more than 100 tons. A lever is a beam connected to ground by a hinge, or pivot, called a fulcrum. The ideal lever does not dissipate or store energy, which means there is no friction in the hinge or bending in the beam. In this case, the power into the lever equals
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
