Document Summary
Element a: since the transverse shear stress at point a is zero, there is no change. Element b: since the only stress at point b is transverse shear stress, neglecting the transverse shear stress ignores the entire stress. Step-3 (c) repeating the process with different beam lengths produces the results in the table. The transverse shear stress is only significant in determining the critical stress element as the length of the cantilever beam becomes smaller. As this length decreases, bending stress reduces greatly and transverse shear stress stays the same. This causes the critical element location to go from being at point a, on the surface, to point b, in the center. The maximum shear stress is on the outer surface at point a for all cases except l. = 0. 1 in, where it is at point b at the center.
