Explanation:

Triple beam balance is the name given to an instrument that is capable of measuring the mass of objects and measuring substances. This instrument is composed of three bundles, as the name says, the front bundle, the middle bundle and the long bundle. These three beams together indicate the difference in people and measurements of the objects in individual analyzes. When the balance of the triple beam is level you will notice that the measured object will not slide out of the pan
