Description
This lever and fulcrum apparatus demonstrates the principle of moments using a 1 m wooden rule that balances at its midpoint on a vertical pillar mounted to a stable table base. It shows that balance occurs when the moment on one side of the pivot, weight multiplied by distance, equals the moment on the other side, giving a clear, measurable introduction to torque and equilibrium.
The 1 m rule includes a knife-edge fitted at the midpoint, and the support includes a V bearing to seat the knife-edge for consistent pivoting. The kit includes two 50 g slotted weight carriers that hook over the edge of a standard metre rule and can be slid to any position along the rule. Standard slotted masses are not supplied, as schools typically already have suitable weights for loading the carriers.
