Calculate mechanical advantage and forces in lever systems
📖 Lever
A lever is a simple machine that uses a rigid bar pivoted at a fulcrum to multiply force. Mechanical advantage = Effort distance / Load distance.
📊 Result
💡 Tips & Information
- Load Force = (Effort Force × Effort Distance) / Load Distance
- Mechanical Advantage = Effort Distance / Load Distance
- Longer effort arm provides greater mechanical advantage
- Three classes of levers based on fulcrum position
- Levers allow lifting heavy loads with less effort
