Compound lever Compound lever The compound lever is a simple machine operating on the premise that the resistance from one lever in a system of levers will act as power for the next, and thus the applied force will be amplified from one lever to the next (as long as the mechanical advantage for each lever is greater than one). Almost all scales use some sort of compound lever to work. Other examples include nail clippers and piano keys. A lever arm uses the fulcrum to lift the load using and intensifying an applied force. In practice, conditions may prevent the use
Lever action the development of its popular hammerless Models 1895 and 1899 (which became named the Model 99) lever-action sporting rifles. The Models 1899/99 were produced from introduction in 1899 until the expense of producing the rifle, and declining interest in lever-action rifles from the 1950s on, resulted in dropping the Model 99 from production in 2000. Unlike most Winchester and the Marlin lever-action rifles, which used a tubular magazine requiring round-nose or flat-nose bullets, Arthur Savage designed his rifle using a rotary magazine. This allowed the 99 to use cartridges with spitzer pointed bullets for increased ballistic performance. The 99 was
