In this episode of Mechanical Engineering Made Simple, we dive deep into the state of equilibrium — the balancing act that keeps the universe, machines, and molecules from falling apart. We’ll break down mechanical and thermodynamic equilibrium, explore stable, unstable, and metastable systems, and unpack how the Second Law of Thermodynamics and entropy define system stability.

Learn how Gibbs free energy and Helmholtz energy act as the bookkeepers of the thermodynamic world — measuring maximum work, energy efficiency, and reaction potential under different conditions. From phase changes to chemical reactions, we translate the math of equilibrium into practical, real-world understanding.

Whether you're studying for your next thermodynamics exam or just love the art of energy balance, this episode grounds you in the physics that keeps everything steady — or sends it spinning out of control.
