Key Features
Graduated metre stick acts as the lever arm.
Millimetre graduations for reading lever-arm distances.
Three knife-edge clamps give low-friction pivot points.
Two mass hangers with 100 g and 200 g weights.
Weighted aluminium stand keeps the set-up steady.

How It Is Used
The metre stick is supported at a knife-edge clamp as the fulcrum and the mass hangers are clamped at measured distances on either side. Students move them until the stick balances, read the distances on the scale and compare clockwise and anticlockwise moments to study torque and static equilibrium.
