SUMMARY
The discussion clarifies that the general conditions of equilibrium for coplanar forces acting at a point differ from those acting on a rigid body. Specifically, while a system of coplanar forces at a point requires the net force to be zero, a rigid body in equilibrium must also satisfy the condition that the net torque about any point is zero. This distinction is crucial for understanding the stability and motion of rigid bodies in physics.
