Continuous beam inflection points
WebHowever, even when f f is continuous and differentiable, it is not enough for the derivative to be 0 0, since this also happens at inflection points: This means finding stable points is a good way to start the search for a maximum, but it is not necessarily the end. Stable points in two variables WebFigure 1, pushes the inflection point out into the span. In the top beam, where both supports are fixed, both inflection points are pushed away from that support. The same tendencies are observed for the left-most beam cases with point load. If the beam were part of a multi-span beam the end-points would neither be fixed nor pinned.
