A lever is a simple machine consisting of a beam or rigid rod pivoted at a fixed hinge, or fulcrum. A lever is a rigid body capable of rotating on a point on itself. On the basis of the locations of fulcrum, load, and effort, the lever is divided into three types. It is one of the six simple machines identified by Renaissance scientists.
The lever is a movable bar that pivots on a fulcrum attached to or positioned on or across a fixed point. The lever operates by applying forces at different distances from the fulcrum, or pivot. The location of the fulcrum determines a lever's class. Where a lever rotates continuously, it functions as a rotary second-class lever.
A lever arm uses the fulcrum to lift the load using and intensifying an applied force.In practice, conditions may prevent the use of a single lever to accomplish the desired result, [1] e.g., a restricted space, the inconvenient location of the point of delivery of the resultant force, or the prohibitive length of the lever arm needed.

A typical helicopter has three flight control inputs: the cyclic stick, the collective lever, and the anti-torque pedals. [2] Depending on the complexity of the helicopter, the cyclic and collective may be linked together by a mixing unit , a mechanical or hydraulic device that combines the inputs from both and then sends along the "mixed ...
Steering wheel with column-mounted gear lever in a W 120-series Mercedes-Benz 180 Column shifter for an automatic transmission in a Ford Crown Victoria. Gear sticks are most commonly found between the front seats of the vehicle, either on the center console (sometimes even quite far up on the dashboard), the transmission tunnel (erroneously called a console shifter when the floor shifter ...
The cam can be seen as a device that converts rotational motion to reciprocating (or sometimes oscillating) motion. [clarification needed] [3] A common example is the camshaft of an automobile, which takes the rotary motion of the engine and converts it into the reciprocating motion necessary to operate the intake and exhaust valves of the cylinders.
Thrust levers in a Boeing 747 Classic. The center and rear levers are used during flight, while the forward levers control reverse thrust.. Thrust levers or throttle levers are found in the cockpit of aircraft, and are used by the pilot, copilot, flight engineer, or autopilot to control the thrust output of the aircraft's engines, by controlling the fuel flow to those engines.
