Compute load force and mechanical advantage from effort and arm lengths.
Results
Load Force (N)
400.00 N
Equivalent Mass: 40.79 kg
Mechanical Advantage
4.00
F₁ × d₁ = F₂ × d₂
The Law of the Lever equates the moments about the fulcrum. Mechanical advantage = d₁ / d₂.
Enter effort force and arm lengths. The calculator shows load force and mechanical advantage automatically.
Effort 100 N at 2 m vs load arm 0.5 m → Load ≈ 400 N, MA = 4.
Q: Does direction matter? A: This computes scalar magnitudes assuming perpendicular forces. Q: Units? A: Use consistent SI units.
