Lever rule

The Lever Rule is a principle used in thermodynamics and materials science to determine the proportions of different phases in a mixture at equilibrium, such as in metals or alloys. Imagine balancing a seesaw: the point where it balances represents the composition of the mixture. In a two-phase system, the Lever Rule helps you find out how much of each phase is present by measuring the distances on either side of the balance point. It’s a useful tool for understanding how different components interact and can inform decisions in manufacturing and material design.
