The columns whose slenderness ratio is less than 80, are known as
A. Short columns
B. Long columns
C. Weak columns
D. Medium columns
Deflection for SSB at central point load=wl^3/48Ei and deflection is inversely proportional to I(bd^3/12).
Hence deflection is also inversely proportional to breadth.
Db/Da = Ba/Bb.
= 1/2.
