1. A state in which an object or system is at rest with all forces balanced, resulting in no acceleration or motion
The ball remains in equilibrium at rest on the flat surface because all forces are balanced.
A bola permanece em equilíbrio em repouso na superfície plana porque todas as forças estão balanceadas.
2. In physics, a condition where the net force and net torque on an object are zero
The bridge achieves equilibrium at rest when the structural forces are perfectly distributed.
A ponte atinge equilíbrio em repouso quando as forças estruturais são perfeitamente distribuídas.
