Question:-
A simply supported beam with width ‘b’ and depth ‘d’ carries a central load W and undergoes deflection d at the center. If the width and depth and interchanged, the deflection at the centre of the beam would attain the value
Option (A)
(d/b) d
Option (B)
(d/b)2d
Option(C)
(d/b)3d
Option(D)
(d/b)3/2
Correct Option:
(B)
Question Solution:
For simple supported beam
deflection (d) = (WL21L22 / 3ElL)
for same load; d a (1/1)
\ d x (1/12)bd3 = d2 x (1/12)b3d
d2 = (d/b)2 d
