Enter the values of effort force, E_{F(N)}, distance from the fulcrum, D_{1(m)} and distance from the fulcrum, D_{2(m) }to determine the value of lever force, F_{L(N)}.

__Lever Force Formula:__

Lever force is the output force exerted by a lever, a fundamental machine that amplifies an input force to lift or move loads. It demonstrates the principle of leverage, where the force applied at one point is magnified at another point by the lever’s mechanical advantage.

The force exerted by a lever, F_{L(N)} in Newton, N is determined by the product of effort force, E_{F(N)} in Newton and distance from the fulcrum, D_{1(m)} in metre is divided by the distance from the fulcrum, D_{2(m)} in metre.

Lever force, F_{L(N)} = E_{F(N)} * D_{1(m)} / D_{2(m)}

F_{L(N)} = lever force in Newton, N.

E_{F(N)} = effort force in Newton, N.

D_{1(m) }= distance in metres, m.

D_{2(m)} = distance in metres, m.

###
- If an effort force of 50N is applied 2m from the fulcrum, and the load is 1m from the fulcrum, calculate the lever force.

Given: E_{F(N)} = 50N, D_{1(m) }= 2m, D_{2(m)} = 1m.

Lever force, F_{L(N)} = E_{F(N)} * D_{1(m)} / D_{2(m)}

F_{L(N)} = 50 * 2 / 1

F_{L(N)} = 100N.

- Suppose we have a lever system where the load force is 300 N, the distance from the fulcrum to the point where the effort is applied is 2 metres, and the distance from the fulcrum to the load is 0.5 metres. We want to find the effort force (EF) required to balance the lever.

Given: F_{L(N)} = 300N, D_{1(m) }= 2m, D_{2(m)} = 0.5m.

Lever force, F_{L(N)} = E_{F(N)} * D_{1(m)} / D_{2(m)}

E_{F(N)} = F_{L(N)} * D_{2(m) }/ D_{1(m)}

E_{F(N)} = 300 * 0.5 / 2

E_{F(N)} = 150 / 2

E_{F(N)} = 75N.
