  • Balanced moments and levers
    • Total anticlockwise moment = total clockwise moment - object will not turn
    • Moment can be increased by
      • Increasing size of force
      • Using spanner with longer handle
    • Levers use balanced moments
    • Levers increase distance from pivot at which force is applied
      • Less force needed to get the same amount
    • LOAD = weight of person
    • EFFORT = force person applies to lever
    • PIVOT = point at which lever turns
    • Levers known as force multipliers
      • Reduce amount of force needed to get same moment by increasing the distance
  • LOAD = weight of person
