Calculate fulcrum position, lever balance, and mechanical advantage for lever systems
š Fulcrum Formulas
Fā Ć dā = Fā Ć dā
MA = dā / dā
Fulcrum Position = (Fā Ć L) / (Fā + Fā)
Torque = Force Ć Distance
Fā,Fā = forces, dā,dā = distances from fulcrum, MA = mechanical advantage, L = total lever length
š” 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
