What is lever balance?

Lever balance refers to a system used to measure weight or mass by balancing an object against known weights on a lever arm. The lever operates on the principle of moments, where the torque produced by the weights on one side of the fulcrum must equal the torque produced by the object on the other side for balance to be achieved. This mechanism allows for precise measurements in various applications, from scientific experiments to weighing goods. Lever balances are often favored for their accuracy and simplicity compared to electronic scales.
