Statics is a branch of mechanics that focuses on the study of forces in systems that are at rest or in a state of equilibrium. In statics, objects are either completely stationary or moving at a constant velocity, meaning there is no net acceleration, and all forces are balanced.

Key aspects of statics include:

1. Equilibrium: In statics, systems are in equilibrium, meaning all forces and moments (torques) acting on an object or system are balanced. This leads to no change in motion—no acceleration or rotation.
2. Force Analysis: Statics involves analyzing and calculating the forces acting on objects to determine conditions of equilibrium. This often includes breaking down forces into components, calculating reaction forces, and analyzing moments or torques.
3. Applications: Statics is widely used in engineering fields like civil, mechanical, and structural engineering, where it’s essential for designing stable structures and systems. Examples include analyzing bridges, buildings, beams, trusses, and support structures, ensuring that they can withstand forces like gravity and wind without moving or collapsing.

Statics is foundational for understanding how structures and objects can remain stable under various force conditions, allowing engineers to design safe, functional, and durable structures and machinery.
