Question

Match List-I (Investigator) with List-II (Equation) and select the correct answer using the codes given below the lists:

List - I	List - II
A. Skempton	1. $v=ki$
B. Coulomb	2. ${\sigma }_1=\sigma -u$
C. Stokes	3. $v=\frac{D^2({\gamma }_s-{\gamma }_w)}{18\eta }$
D. Terzaghi	4. $s=c+\sigma tan\Phi$
	5. $u=B[{\sigma }_3+A({\sigma }_1-{\sigma }_3\left)\right]$

Codes
$ABCD$

• A. $4532$
• B. $5432$
• C. $4513$
• D. $5423$

Answer 1

The correct option is B $5432$

Terzaghi gave effective stress principle. Effective stress.
${\sigma }^{\prime }=\sigma -u$
Where $\sigma$ is total stress and $u$ is pore pressure
