201. The water content in a soil at which just shear strength develops is called-
liquid limit
elastic limit
plastic limit
shrinkage limit
202. The coefficient of permeability of slit is---that of clay.
same as
less than
more than
none of these
203. A flow net is used to determine the-
seepage flow
seepage pressure
exit gradient
all of these
204. The liquidity index (in percentage) is given by-
ব্যাখ্যা: Here, ω = Natural water content ω_p = Plastic limit I_p= Plasticity index
(ω_p-ω)*100/I_p
(ω_L-ω)*100/I_p
(ω_L-ω_p )*100/I_p
(ω-ω_p )*100/I_p
205. The liquid limit minus plastic limit is termed as-
flow index
plasticity index
shrinkage index
liquidity index
208. The unconfined compressive strength of a very soft clay is-
10 to 25kN/m²
150 to 400kN/m²

210. The critical gradient of the seepage of water--- with the increase in S.G. of soil.
increases
decreases
same
infinity
211. Shrinkage index কী? [MOCA-19]
ব্যাখ্যা: মৃত্তিকার তারল্য সীমা এবং সংকোচন সীমার পার্থক্যকে সংকোচন সূচক বলে। অর্থাৎ, SI = LL - SI Shrinkage index = Liquid limit - Shrinkage limit.
Liquid limit - Shrinkage limit
Liquid limit + Plastic limit
Plastic limit - Liquid limit
Shrinkage limit - Liquid limit

((G+e)γ_ω)/(1+e)
((1+e)γ_ω)/(G+e)
((G-1)γ_ω)/(1+e)
((1-e)γ_ω)/(G+e)
215. When the consistency index is zero, then the soil is at its-
elastic limit
