Quick Summary

Stability, in the context of structures, refers to their ability to withstand forces and stress without being damaged or dislodged. This is achieved when a structure is in a state of equilibrium, meaning there is no net force or torque acting upon it. Forces acting on a structure include its own weight and any loads it carries. These forces are counteracted by opposing forces at its joints, ensuring the structure remains balanced.123

The study of bodies and structures in equilibrium is called statics. A key application of statics is analyzing the stability of buildings and bridges, considering factors like gravity and the strength of materials used. For instance, materials like stone and brick are strong under compression but weak under tension, influencing their use in construction. Ultimately, a structure's stability relies on diverting all loads downward to be supported by the ground.23
