Unequal-arms scale Manufacturer,Supplier and Exporter in India
Product Code : SCL-MH-12641
The Unequal-Arms Scale by Educational Instrument India is a practical physics laboratory apparatus designed to demonstrate the principle of moments, equilibrium of a lever, torque, and mechanical advantage. It is widely used in school physics laboratories, STEM classrooms, science demonstrations, and mechanics experiments.
This apparatus helps students understand how balance can be achieved when different masses are placed at different distances from the fulcrum. By using unequal arms, learners can clearly observe the relationship between load, effort, distance, and turning effect in a lever system.

How to Use Unequal-Arms Scale
Place the Unequal-Arms Scale on a stable and flat laboratory table.
Ensure the scale is properly balanced before starting the experiment.
Place a mass on one side of the lever arm at a selected distance from the fulcrum.
Place another mass on the opposite side at a different distance from the fulcrum.
Adjust the mass position until the lever becomes balanced.
Record the values of mass and distance on both sides of the fulcrum.
Verify the law of moments using the formula: Moment = Force × Distance.
Repeat the experiment with different masses and distances to compare results.
