SUMMARY
Beam bending occurs primarily about the centroidal axis due to the distribution of stress within the beam's cross section. The moment of inertia, calculated around this centroidal axis, quantifies the beam's resistance to bending. During bending, portions of the beam experience tension while others experience compression, with the centroidal axis representing the neutral axis where no stress occurs. This fundamental principle is crucial for understanding beam behavior in structural engineering.
