SSC RSMSSB JE Mock Test 2024 Soil Mechanics and Foundation Engineering Site Investigation and Sub-Soil Exploration
If D1 & D2 are inside and outside diameters of the cutting edge then the Area ratio of the sampler is determined using the relation:
1
\(\frac{D_2^2 - D_1^2}{2D_1^2} \times 100\)
2
\(\frac{D_2^3 - D_1^3}{D_1^2} \times 100\)
3
\(\frac{D_1^2 - D_2^2}{D_1^2} \times 100\)
4
\(\frac{D_2^2 - D_1^2}{D_1^2} \times 100\)
