Right @Vipsai.

Eccentricity =one side distance from centre.
=D/8 (radius).

For dia. to make circle= D/8 + D/8.
= D/4.

Vipsai said:   5 years ago
We all know that Limit of Eccentricity for a circle is D/8 on either side of the Y-Y axis, which means D/8 + D/8 = D/4.

So, the load is limited to the radius of D/4 of the circle.

Right, agree @Subham Verma.

The answer will be C.

As we know, e less than or equals to d/8 for the circular section.
and as e is distance b/w centre line and max. possible pt. of no tension condition
therefore, e=r for that assumed circular section.
And r less than or equals to d/8.
Which implies r' = d/8 or d = d/4.

The Answer should be D/8, which means 1/8. S, Option D is correct.

I agree @Anirudh.

I think it's for eccentric loading.

The area where if force acts, no tensile force is created is called Kern area. It is d/4 (circular area) for a circular column and diamond (diagonals d/3 & d/3) for a rectangular column.
