What is the ratio of maximum deflection to maximum bending stress if a simply supported rectangular beam of span “L” and it carries a central load W.

What is the ratio of maximum deflection to maximum bending stress if a simply supported rectangular beam of span “L” and it carries a central load W. Correct Answer L2/ 6 Ed

Maximum deflection in simply supported beam is y = Wl2/48EI y= Wl3/48E (bd3/12) y/f = l2/ 6Ed.
