A first-class lever can have a mechanical advantage greater than, equal to, or less than 1, depending on the relative distances between the fulcrum, effort force, and load. It does not inherently have a high mechanical advantage.
A class 2 lever can have a mechanical advantage (MA) greater than one. In this type of lever, the load is situated between the fulcrum and the effort, allowing for an increased output force compared to the input force applied.
To increase the mechanical advantage (MA) of a lever, you can either increase the length of the lever arm or decrease the length of the load arm. Both of these changes will result in a higher MA, making it easier to lift a heavier load.
The mechanical advantage formula for a 1st class lever is calculated by dividing the distance from the fulcrum to the input force by the distance from the fulcrum to the output force. Mathematically, M.A = input arm length / output arm length.
Mechanical Advantage is given by the following equation: MA = Load Effort On a class 2 lever, the fulcrum (pivot) is at one end of the lever and the work applied is at the other end. The load is then applied near the fulcrum, as common with the wheel barrow. A class 3 lever has the effort applied between the fulcrum and the resistance. Therefore, a much greater effort will be required to produce the same moment value. A typical C2 lever has a much greater distance in which to produce the load than a C3 lever.
To find the mechanical advantage (MA) of a lever, you can calculate it by dividing the length of the effort arm by the length of the load arm. The formula is MA = Le / Ll, where Le is the length of the effort arm and Ll is the length of the load arm.
Class-III Lever . . . MA always less than 1. Class-II Lever. . . . MA always more than 1. Class-I Lever . . . . MA can be 1, more than 1, or less than 1.
It is (distance from fulcrum to effort)/(distance from fulcrum to load).
A class 2 lever can have a mechanical advantage (MA) greater than one. In this type of lever, the load is situated between the fulcrum and the effort, allowing for an increased output force compared to the input force applied.
Mechanical advantage: Class-I lever . . . can be any positive number Class-II lever . . . always less than ' 1 ' (and more than zero) Class-III lever . . . always more than ' 1 '
The ideal MA is 47.
Move the fulcrum farther from the force and closer to the load.
