Beam Bending & Deflection
Size a simply supported beam from first principles and inspect how the load case changes reactions, shear, bending moment, and midspan deflection.
Beam Response
The load diagram shows how the beam is supported and loaded; the charts below show the resulting internal shear, bending moment, and deflected shape along the span.
