What is the rigorous mathematical principle for: Equilibrium of a Rigid Body in Classical Statics?
Static equilibrium requires only that horizontal forces balance out (Σ F_x = 0)
A rigid body is in complete static equilibrium if and only if both resultant force vector equals zero (Σ F = 0) and total algebraic moment about any point equals zero (Σ M = 0)
Moment of a force is a scalar quantity independent of perpendicular distance
A body is in equilibrium if it rotates with constant angular acceleration
