What represents the balance between gravity and outward fusion pressure in a star?

Answer

Hydrostatic equilibrium

Hydrostatic equilibrium is the stable state achieved during the main sequence of a star's life. In this condition, the inward crushing force of the star's own gravity is perfectly counteracted by the outward pressure produced by nuclear fusion occurring in the core. This balance allows the star to remain stable for a significant period.
