Question:-
A short column of symmetric cross-section made of symmetric cross-section made of a brittle material is subjected to an eccentric vertical load P at an eccentricity e. To avoid tensile stress in the short co1umn the eccentricity e should be less than or equal to
Option (A)
h/12
Option (B)
h/6
Option(C)
h/3
Option(D)
h/2
Correct Option:
(B)
Question Solution:

Direct stress (s1) = (P/bh)
Bending stress (s2) = (6Pe/bh2)
total stress on CD
= -s1 + s2 = -(P/bh) + (6Pe/bh2) = 0
e = h/6
