# Effort Force Calculator, Formula, Force Calculation

## Effort Force Calculator:

Enter the values of load force, LF(N), distance from the fulcrum to the point where the load force is applied, D1(m) and distance from the fulcrum to the point where the effort force is applied, D2(m) to determine the value of effort force, EF(N).

 Enter Load Force: N Enter Distance1: m Enter Distance2: m Result – Load Force: 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, D1(m) in metres by distance from the fulcrum to the point where the effort force is applied, D2(m) in metres.

Effort force, EF(N) = LF(N) * D1(m) / D2(m)

EF(N) = effort force in Newton, N.

LF(N) = load force in Newton, N.

D1(m) = distance in metres, m.

D2(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, D1(m) = 2m, D2(m) = 8m.

Effort force, EF(N) = LF(N) * D1(m) / D2(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, D1(m) = 2m, D2(m) = 10m.

Effort force, EF(N) = LF(N) * D1(m) / D2(m)
