A cantilever beam of rectangular cross section (depth ‘d’, width ‘b’ & length ‘L’) is subjected to a shear force ‘F’ at its free end as shown in figure. The beam is made of material which follows maximum shear stress theory. Which of the following is TRUE?

A

The beam section has a uniform shearstress, $$\frac{F}{bd}$$

B

Maximum shearstress in section and maximum bending stress in beam is equal when $$L = \frac{d}{2}$$

C

For $$L > \frac{d}{2}$$, bending stress decides the failure stress.

D

Bending stress developed in the beam is independent of ‘b’
