Levers are a class of simple machines, the other five classic types being gears (wheel and axle), pulleys, inclined planes, wedges and screws. Levers allow for force multiplication, and compound levers all the more so. Compound lever examples include pia
Simple machines are usually divided into two types: inclined planes (ramps, screws, wedges) and levers (levers, wheel and axle, pulleys). A lever is a bar that rests on a turning point (or pivot). Levers can help you lift objects. A pulley is also used to lift objects. Instead ...
Locate the position of the fulcrum in relation to where the load sits and where the force is applied. A first-class lever will have the load and the force exerted to move the load on opposite sides of the fulcrum. Examples of a first-class lever include teeter totters, the claws of a...
