If the beam in Problem 1 is required to have a constant width, but is allowed to change in height along the beam, what would be the geometry that would give rise to a constant bending stress along the top fiber of the beam?

Problem 1

If the cantilever beam shown in Fig. 1 is shortened until the effect of transverse shear is equal to the effect of maximum bending stress, what will be the length of the beam? What general guideline could you conclude about when it is important to consider the effects of transverse shear on a cantilever beam?
