👉 Balance math, or statics in physics, deals with the equilibrium of forces acting on a body at rest, where the sum of all forces and the sum of all torques (rotational forces) acting on it are zero. This means that for a system to be in static equilibrium, the net force must equal zero, and the net torque around any point must also be zero. This principle allows us to analyze and predict how objects remain stable under various forces, such as gravity, friction, and applied loads, without moving. By applying balance math, engineers and physicists can design structures and systems that remain stable and functional under different conditions.
