How does a beam balance work? ill mark u brainliest if ur answer is correct
Answers
A beam balance is the simplest instrument to measure mass (weight). In a beam balance, the mass of an object is measured by comparing it with standard masses called standard weights. A simple beam balance consists of a straight beam of metal (generally iron), supported at its center with the help of an iron loop. A pointer is fixed at the center of the iron loop. Two identical pans are suspended at equal distances from the center, at the two ends of the beam. The object whose mass has to be measured is placed on one of the pans (generally the right pan). Standard weights are placed on the other pan until the metallic beam becomes horizontal and the pointer becomes vertical. The sum total of all weights used gives the mass of the object. there are two pans suspended by a hook and separated by equal distances from the center. There is another hook in the center to support and hold the balance. The object whose mass has to be measured is placed on one of the pans. Standard weights are placed on the other pan until the metallic beam becomes horizontal and the pointer becomes vertical. The sum of the total of all weight used gives the mass of the object. A beam balance works on the principle of moments according to which in equilibrium, the anticlockwise moment due to the weight of an object on the left pan of the beam is equal to the clockwise moment due to the standard weights of the right pan of the beam. The principle of moment states that when a body is balanced, the clockwise moment about a point equals the total anticlockwise about the same point.
