ANSWER: E. One-sixth of the base on either side of the centroid.

MIDDLE THIRD RULE FOR RECTANGULAR SECTION The range within which the load may be applied so as not to produce tensile stress anywhere in the section is within the middle third of depth Limiting eccentricity 6/40.

Vipin sainath said:   5 years ago
Option E is correct, For rectangular section, the limit of eccentricity is " e <= b/6 or d/6 on either side of the centroid" and For Circular section, the limit of eccentricity is " e<= D/8 on either side of the centroid".

Refer RK Bansal.

For rectangular column.

limit of eccentricity=z/a ,z=bd3/12*d/2.
A=b*d.
:For rectangular column, e=d/6.
For circular column, e=d/8(by z/A).

Answer should be (1/3) of base.

If applied load follows middle one by third rule then no tensile stresses are produced.

Check it out.

For Rectangular section:
e<=b/3

And
e<=d/6 or h/6

For circular section
e<=d/8
So, the given answer is correct.

DHAWAL KALRA said:   1 decade ago
Correct option is E. As it forms the rhombus as given area, 1/3 can be the answer if we take whole among the base.

Overall kern zone lies in one-third dimension for square and rectangle so d/6 or b/6 on every side on center.

Deepak raj joshi said:   1 month ago
(b or d)/3 for rectangle.
R/4 for circle.
These regions refer to kern size or core size.

It will be 1/3rd of the base OR 1/6th of the base on either side of the centroid.

1/6th of base from the centroidal axis is the correct answer.
