- 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
