Question

A tapered cantilever beam AB of length L has
square cross sections and supports a concentrated
load P at the free end (see figure part a). The width
and height of the beam vary linearly from hA at the
free end to hB at the fixed end.
Determine the distance x from the free end A to the
cross section of maximum bending stress if hB = 3hA.
(a) What is the magnitude σmax of the maximum
bending stress? What is the ratio of the maximum
stress to the largest stress B at the support?
(b) Repeat part (a) if load P is now applied as a uniform
load of intensity q = P/L over the entire
beam, A is restrained by a roller support, and
B is a sliding support (see gure part b).
