40.

The total active earth pressure due to dry back fill with no surcharge, acts at H/3 above the base of the wall and is directly proportional to

 [A]. H [B]. [C]. H2 [D]. H3.

Explanation:

No answer description available for this question.

 Kunal said: (Jan 10, 2017) Why not A?

 Mahesh said: (May 14, 2017) p = 1/2 w h^2.

 Mmm said: (Jun 17, 2017) It is asking for pressure not thrust. It should be A.

 Raju said: (Dec 23, 2017) p = 1/2 w h^2cotθ

 Sukumar said: (Feb 22, 2019) It is pressure, not active force. So, the answer is "A".

 Junaid Khan said: (Oct 28, 2019) pa = 1/2 karH^2.

 Abhi said: (Jul 14, 2020) Pa = Ka * H, So, Why not Option A?

 Paramjit Paul said: (Feb 15, 2021) Pa=1/2Ka.YH^2. Where Pa = Active earth pressure force on a unit length of the wall.

 Shuva Halder said: (May 24, 2021) D. H^3, Because, The active earth pressure with no surcharge Pa=1/2.ka.Y.h^2 acts above the H/3. Pa= 1/2.ka.Y.H^2.H/3.
