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 the Winchester Model 1895 as a military weapon. Early attempts at repeating shotguns invariably centered around either bolt-action or lever-action designs, drawing obvious inspiration from the repeating rifles of the time. The earliest successful repeating shotgun was the lever-action Winchester Model 1887, designed by John Browning in 1885 at the behest of the Winchester Repeating Arms Company, who wanted to market a repeating shotgun. The lever-action design was chosen for reasons of brand recognition, Winchester being best known for manufacturing lever-action firearms at the time, despite the protestations of Browning, who pointed out that a slide-action design would be much
