Calculate fulcrum position, lever balance, and mechanical advantage for lever systems
📐 Fulcrum Formulas
F₁ × d₁ = F₂ × d₂
MA = d₁ / d₂
Fulcrum Position = (F₂ × L) / (F₁ + F₂)
Torque = Force × Distance
F₁,F₂ = forces, d₁,d₂ = distances from fulcrum, MA = mechanical advantage, L = total lever length
💡 Tips
- Fulcrum position affects mechanical advantage
- Longer effort arm increases mechanical advantage
- Balance torques for equilibrium
- Consider friction and efficiency losses
- First class levers can amplify or reduce force
- Second class levers always amplify force
