The IEC Lever & Fulcrum is a simple demonstration where a metre rule balances at its mid point on a vertical pillar mounted on a base to rest on the table. It shows that when the weight x the distance (the moment) on one side of a pivot point equals the weight x distance on the other side, the system balances because the 2x moments are equal.
This kit includes 2x 50g special slotted weight carriers that hook over the edge of a standard metre rule and can be slid to any point. Because schools have many suitable weights, the slotted weights themselves are not supplied. The 1m wooden rule has a knife-edge fitted at the mid point and the support has a vee bearing to take the knife-edge.

Kit contains:
1 pce. Base (with the end mouldings removed) with ‘Fulcrum’ (vertical upright with ‘vee’ groove)
1 pce. Lever. Balanced metre rule with knife edge fitted
2 pcs. 50gm brass weight hangers to be positioned along the rule.

NOTE: Slotted weights are not supplied with this kit.
