Balancing Equal Torques
Fix the centre pivot to a stand and level the lever with the end balancing weights. Hang hooked masses on both sides and move them until the lever settles horizontal. At balance, mass times distance from the pivot is the same on each side, which is the principle of moments: a 50 g mass at 20 cm balances 100 g at 10 cm.
Finding the Torque of the Lever Itself
Move the pivot near one end and the lever no longer balances on its own, because its weight acts at its centre, now some distance from the pivot. Adding a known mass on the short side until the lever levels out measures that torque, and dividing it by the distance from the pivot to the centre gives the weight of the lever.
