How a Beam Balane is used?

A beam balance is used to measure the mass of objects by comparing them against known weights. It consists of a horizontal beam that is pivoted at its center, with two pans on either side where the object and standard weights are placed. When the weights on both sides are equal, the beam is level, indicating that the mass of the object matches the total mass of the weights. This method allows for precise measurement of mass, as it relies on the principle of equilibrium.
