A lever is a simple machine consisting of a beam or rigid rod pivoted at a fixed hinge, or fulcrum. Classified into three types based on the location of fulcrum, load, and effort, levers amplify input force to provide a greater output force, creating leverage. The mechanical advantage of a lever is the ratio of the output force to the input force.
Classes of levers:
1. Class 1: Fulcrum in the middle - effort on one side, load on the other (e.g., seesaw, crowbar).
2. Class 2: Resistance in the middle - effort on one side, fulcrum on the other (e.g., wheelbarrow, nutcracker).
3. Class 3: Effort in the middle - load on one side, fulcrum on the other (e.g., tweezers, human mandible).
Mechanical advantage is a measure of force amplification. It's expressed by the law of the lever, where the moment action on both sides is equal:
Fe x De = Fl x Dl
Where:
- F_e = effort force (N, lb)
- F_l = load force (N, lb)
- D_l = distance from load force to fulcrum (m, ft)
- D_e = distance from effort force to fulcrum (m, ft)
The effort force can be calculated using the formula:
Fe = Fl x Dl / De
Fe = m x g x Dl / De
where
m = mass (kg)
g = acceleration of gravity (9.81 m/s²)
