The range within which a load can be applied on a rectangular column, to avoid any tensile stress, is

[A]. one-half of the base
[B]. one-third of the base
[C]. one-fourth of the base
[D]. one-fifth of the base
[E]. one sixth of the base on either side of centroid.

Answer: Option B

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.

Ckumar said: (Aug 21, 2014)  
Yes answer will be 1/3 or 1/6 both side from centre.

Virendra Singh said: (Feb 1, 2015)  
1/6 of the base on either side of centroid.

Dhawal Kalra said: (Jul 8, 2015)  
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.

Ajinkya said: (Sep 16, 2015)  
1/6 is correct answer. It is core of section.

Ajaychelkar512 said: (Dec 4, 2015)  
Yes. 1/6th is the correct answer.

Jayapal said: (Apr 28, 2016)  
The correct answer is 1/6th of the base.

Krishna said: (May 12, 2016)  
1/6th of base from the centroidal axis is the correct answer.

Subhankar said: (Aug 6, 2016)  
Why 1/6? It should be 1/3.

Samm said: (Aug 30, 2016)  
Agree with you @Dhawal.

E is the answer.

Dalisha said: (Sep 22, 2016)  
I think it should be E.

Ramanareddy said: (Sep 24, 2016)  
e < d/6 = there is no tension failure.

Jwala said: (Oct 25, 2016)  
Overall kern zone lies in one-third dimension for square and rectangle so d/6 or b/6 on every side on center.

Denzil said: (Dec 2, 2016)  
I agree and the correct option is E.

Shravan said: (Apr 17, 2017)  
Answer E. The Correct answer e<b/6.

Deb said: (Jun 18, 2017)  
It is given range. So it will be 1/3 rd "Middle third rule".

Shiroya Manish said: (Jul 5, 2017)  
For rectangular column.

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

Sheela said: (Aug 9, 2017)  
Please give the correct answer.

Shiva said: (Sep 23, 2017)  
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.

Sai Madhav said: (Sep 24, 2017)  
For avoid tensile stresses eccentricity < b/6.

Pankaj said: (Oct 12, 2017)  
1/4 is correct.

Ritu said: (Jan 9, 2018)  
It will be 1/3rd of the base OR 1/6th of the base on either side of the centroid.

Bunty said: (Jun 20, 2018)  
Well said @Ritu.

Harsha said: (Dec 11, 2018)  
Yes, option E is correct.

Udit Narayan said: (Feb 6, 2019)  
E is the correct answer.

Chandan Yadav said: (Jun 23, 2019)  
E is the correct answer.

Nadhiya said: (Aug 1, 2019)  
Answer shall be 1/3 of base.

Aishwarya said: (Jan 14, 2020)  
E is the correct answer. I too agree.

Vipin Sainath said: (Apr 9, 2020)  
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.

Saqib said: (Apr 16, 2020)  
The correct answer is 1/6.

Birendra Kumar said: (May 4, 2021)  
1/6 is the correct answer for the rectangle.
