S2. Ans.(c)
Sol. Ultimate bearing capacity (q_u ) = CN_c+ qN_q + 0.5B_r N_r
For cohesive soil
C=10 kN\/m²
Net ultimate bearing capacity (q_nu ) =?
= 10 ×5.7
=57 kN/m²

S3. Ans.(b)
Sol. The concrete in which no reinforcement is provided called plain concrete. Plain concrete is strong in taking Compressive stresses. The tensile strength of concrete is 10 to 15% of compressive strength.

S4. Ans.(b)
Sol. 1 cm = 4 m
1 cm = 400 cm
▭(Fractional scale=1/400=1:400)

S5. Ans.(b)
Sol. Measured length of line (L’) = 327 m.
Length of tape (l) = 20 m.
True length of tape (l’) = 20 + 0.03 = 20.03 m.
True length of line (L) =?
L × l = L’ × l’
L × 20 = 327 × 20.03
L = (327×20.03)/20

S6. Ans.(d)
Sol. Given, Porosity (n) = 40% = 0.4
Void ratio (e) = ?
