statics
Sign in to saveStatics is the branch of classical mechanics that is concerned with the analysis of force and torque acting on a physical system that does not experience an acceleration, but rather is in equilibrium with its environment.
AI overview
Statics is the branch of physics that studies forces and twists (called torques) acting on objects that aren't accelerating—in other words, objects that are stationary or moving at a constant speed. It matters because understanding these balanced forces helps engineers and builders design safe structures like bridges and buildings that won't collapse or tip over.

Statics is the branch of classical mechanics that is concerned with the analysis of force and torque acting on a physical system that does not experience an acceleration, but rather is in equilibrium with its environment.
If \textbf F is the total of the forces acting on the system, m is the mass of the system and \textbf a is the acceleration of the system, Newton's second law states that \textbf F = m \textbf a \, (the bold font indicates a vector quantity, i.e. one with both magnitude and direction). If \textbf a =0, then \textbf F = 0. As for a system in static equilibrium, the acceleration equals zero, the system is either at rest, or its center of mass moves at constant velocity.
