Weighing scale

A scale or balance is a device to measure weight or mass.These are also known as mass scales, weight scales, mass balances, weight balances.. The traditional scale consists of two plates or bowls suspended at equal distances from a fulcrum.One plate holds an object of unknown mass (or weight), while known masses are added to the other plate until static equilibrium is achieved and the plates.
