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 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
