Answer (1)
A triple-beam balance is a type of mechanical balance used to measure mass. It gets its name from having three beams, each with a different movable weight or rider. The weights are slid along the beams to achieve equilibrium with the object placed on the pan. The mass of the object is determined by adding the values indicated by the positions of the three weights. The three beams are typically graduated in different increments, such as 100 grams, 10 grams, and a fractional gram scale, allowing for precise measurements.
