A short column of external diameter D and internal diameter 'd' carries an eccentric load W. The greatest eccentricity which the load can have without producing tension on the cross section of the column, would be
1
\(\rm\frac{D^2+d^2}{8 d}\)
2
\(\rm\frac{D+d}{8}\)
3
\(\rm\frac{D^2+d^2}{8}\)
4
\(\rm\frac{D^2+d^2}{8 D}\)
