Beam balance
Pots were used to measure grain in various parts of the world in ancient times.[1]A beam balance is a device used to measure mass. An object is put into a disk on one side that hangs from one end of a bar. It is balanced with weights at the other end. It has a lever at the middle just for support with two equal arms and a pan suspended from each arm at the end of the beam by equal length of strings. More so it can be used to measure various object. It is a very useful machine. It is used by shopkeepers to weight the material which the customer is buying.
A beam balance is a type of scale that uses a beam with weights suspended from it's ends to measure the weight or mass of an object. The object to be weighed is placed on one end of the beam, and weights are added to the other end until the beam is in equilibrium, meaning that the two sides are balanced. They are designed to measure the weight or mass of an object by suspending it from a beam.

For a simple pan balance to be in equilibrium, the fulcrum must be offset from the lever arm. When this is the case, the higher arm gains a mechanical advantage over the lower because its horizontal separation from the fulcrum is greater.
