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, 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.
