A simply supported beam of span L carries a UD load of w/m. Find the variation in depth, keeping the width constant, of a rectangular section for constant strength. Sketch the plan and section of the beam.

A cantilever beam carries a concentrated load at its free end. Neglecting the self weight of the beam, find the variation in diameter of a solid circular section, to have a beam of constant strength.
