Effortlessly determine the mechanical advantage of any lever using our no-cost online tool. Swift and straightforward – obtain the desired advantage within seconds!
Mechanical advantage quantifies the energy conservation achieved through tool or automatic device utilization. In essence, it signifies the gain realized when employing an automated system for force transmission. The lever ranks among the most commonly utilized simple machines that offer mechanical advantage. This online tool is designed to calculate the mechanical advantage of the three distinct classes of levers.
Mechanical Advantage of a Lever formula
Mechanical Advantage of First Class Lever
![\[MA = \frac{d_1}{d_2}\]](https://x-calculator.com/wp-content/ql-cache/quicklatex.com-2c64c8300cc6f6840eceabda614e84af_l3.png "Rendered by QuickLaTeX.com")
Mechanical Advantage of Second Class Lever
Mechanical Advantage of Third Class Lever

Where:
- MA = Mechanical Advantage
- d1 = Effort Arm
- d2 = Load Arm
Levers are classified according to the position of the fulcrum, input and output forces. A first class lever has the fulcrum in the middle and the effort applied on one side and the load on the other. A second class lever has the load in between the effort and the fulcrum. A third class lever has the effort in between the load and the fulcrum.
For example, if the effort arm is 5 and the load arm is 7, then the mechanical advantage of a first or second class lever is 5/7 = 0.7143, while the mechanical advantage of a third class lever is 7/5 = 1.4.
