Abstract

In fact, mass of a body is difficult to determine, but it can be compared easily against a body of known mass. This process of comparing the masses of two bodies is commonly known as weighing process. The weighing is carried out through a balance. The balances can be broadly divided into two groups, namely (1) two-pan balance and (2) single-pan balance. In this chapter, we will consider two-pan, equal-arm balance.
