Deflection WL^3/8EI.
I= Bd3/12.
hence Depth ratio = D^3/(2D)^3 = 0.8^3/(2*0.8)^3 = 0.125.
I= Bd3/12.
hence Depth ratio = D^3/(2D)^3 = 0.8^3/(2*0.8)^3 = 0.125.

DEFLECTION = PL^2/EI.
I= BD^3/12.
I proportional to D^3;
X=BD^3/8EI.
.8/X = 8,
X= 0.1.
I= BD^3/12.
I proportional to D^3;
X=BD^3/8EI.
.8/X = 8,
X= 0.1.
