Abstract
Balances are accurate and precise instruments used to measure the weight or mass of a substance or material. The ability to measure material as large as 50kg and as small as 10μg makes them quite common.
There are two main categories of balances, mechanical and electromagnetic. Mechanical balances tend to be the simpler of the two. They generally consist of springs or lever arms, and use either a known force or mass to determine the unknown measurement.
