Compound lever the force of pushing back the stick to the levers and they rub against the wheels, using friction to slow and eventually stop the train. These are everyday applications of this mechanism. A piano key is a compound lever of the first-class, since the fulcrum is between the weight to be moved and the power. The purpose of this lever is to translate a small movement (depression of the key) into a larger and fast movement of the hammer on the strings. The quality of the resulting tone depends on whether the final speed is brought about by gradual or
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
