Solid Mechanics — Bending Moment and Shear Force Diagrams + 6 more topics

When a beam is subjected to external loads (like weights or pressures), internal forces develop within its cross-section to resist these loads. These internal forces are primarily shear force (V) and bending moment (M).

When a beam is subjected to a bending moment, internal stresses develop within its cross-section. These stresses are known as bending stresses (or normal stresses due to bending).
