Statics is a fundamental branch of mechanics concerned with the analysis of bodies in equilibrium—that is, objects that are either at rest or moving at a constant velocity. It analyzes the forces and moments acting upon a rigid body to determine if and how that body maintains a state of balance. The core principles involve defining the conditions necessary for equilibrium, which state that the vector sum of all external forces acting on the body must be zero, and similarly, the sum of all moments (or torques) about any point must also be zero. The study is essential in engineering fields such as civil and mechanical engineering for designing structures, bridges, and machine components that must withstand applied loads and environmental forces without undergoing unintended motion or structural failure.
