## Effort Force Calculator:

Enter the values of load force, LF_{(N)}, distance from the fulcrum to the point where the load force is applied, D_{1(m)} and distance from the fulcrum to the point where the effort force is applied, D_{2(m)} to determine the value of effort force, EF_{(N)}.

__Effort Force Formula:__

Effort force is the force applied to a simple machine, such as a lever or pulley, to move a load. It’s the input force that works against resistance to achieve mechanical advantage.

Effort force, EF_{(N)} in Newton is equated by dividing the product of load force, LF_{(N)} in Newton and distance from the fulcrum to the point where the load force is applied, D_{1(m)} in metres by distance from the fulcrum to the point where the effort force is applied, D_{2(m)} in metres.

Effort force, EF_{(N)} = LF_{(N)} * D_{1(m)} / D_{2(m)}

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

LF_{(N)} = load force in Newton, N.

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

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

__Effort Force Calculation:__

1. Suppose you need to lift a 200 Newton load using a lever. The distance from the fulcrum to the load (D1) is 2 metres, and the distance from the fulcrum to where you apply the effort (D2) is 8 metres. Calculate the effort force required.

Given: LF_{(N)} = 200N, D_{1(m)} = 2m, D_{2(m)} = 8m.

Effort force, EF_{(N)} = LF_{(N)} * D_{1(m)} / D_{2(m)}

EF_{(N)} = 200 * 2 / 8

EF_{(N)} = 400/8

EF_{(N)} = 50N.

2. Suppose the effort force required to lift a load using a lever is 75 Newtons. The distance from the fulcrum to where you apply the effort (D2) is 10 metres, and the distance from the fulcrum to the load (D1) is 2 metres. Calculate the load force.

Given: EF_{(N)} = 75N, D_{1(m)} = 2m, D_{2(m)} = 10m.

Effort force, EF_{(N)} = LF_{(N)} * D_{1(m)} / D_{2(m)}

LF_{(N)} = EF_{(N) }* D_{2(m)} / D_{1(m)}

LF_{(N)} = 75 * 10 / 2

LF_{(N)} = 375N.
