Where along the span is M_max?

For SS center load it is midspan; for SS UDL midspan; for cantilever cases at the fixed end.

Only magnitudes are shown for simplicity.

Shear & Bending Moment Calculator

Reports peak |V| and |M| for the same four ideal cases as the deflection companion: mid-span point load, uniform load on simply supported beam, tip point load on cantilever, and uniform load on cantilever. Not a full shear/moment diagram tool.
