How Do You Find The Mechanical Advantage For A Lever?
The lever is one of the six simple machines. It is made of a board or rigid object that pivots around a fulcrum. The lever works by transferring an applied force over a distance and exerting an output force on an object. The lever increases the magnitude of the output force by sacrificing the distance this force is applied over. The effectiveness of the lever can be shown by calculating the mechanical advantage (MA) for the lever. Identify the fulcrum. This will be the point about which the the board or rigid object pivots around. Identify the locations of the input and output forces. The input force is the force that is applied to the lever, oftentimes by a machine or human. The output force is the force that the lever exerts onto an object. Find the distance between the fulcrum and the input force. This is known as the resistance arm. Find the distance from the fulcrum to the output force. This is known as the effort arm. Divide the length of the effort arm by the length of the resis
