We can either calculate the elasticity at a specific point on the supply curve, known as point elasticity or between two prices, known as arc-elasticity. Within the limit of elasticity, the stress is proportional to the strain. When the price falls he buys 1400 units. y = FΔl / Al = Mg Δl / πr 2 l. Its unit is N/m 2 or Pascal and its dimensional formula is [ML-1 T-2]. Following formula is used to measure the Price elasticity of demand. (a) Solid:- It is the type of matter which has a definite shape and a definite volume. So far we have seen that the concept of elasticity of supply is similar to that of elasticity of demand.
