Soil Mechanics MCQ Paper-2 Welcome to your soilmechanicsmcqpaper-2 1. The soil transported and deposited by a river or a stream are called Lacustrine soil Alluvial soil Marine soil Aeolian soil None 2. The water content where further loss of moisture will not result in any soil volume reduction is known as plastic limit plasticity index liquidity index shrinkage limit None 3. A soil sample has porosity 25%. Calculate its void ratio 3.00 0.46 0.65 0.34 None 4. Water content of a soil sample can be determined by alcohol method sand replacement method jar test method shrinkage limit method None 5. Uniformity coefficient of a soil is always less than 1 always equal to 1 equal to or less than 1 Equal to or greater than 1 None 6. Water content of soil can be less than 0% be greater than 100% never be greater than 100% take values only from 0% to 100% None 7. The volume of voids to the total volume of soil is known as Porosity void ratio air ratio air content None 8. When the plastic limit of a soil is greater than the liquid limit, then the plasticity index is reported as one negative zero non-plastic None 9. Water content of a soil sample is the difference of the weight of the given sample at the given temperature and the weight determined after drying it for 24 hours at temperature ranging from 80⁰C to 90⁰C 105⁰C to 110⁰C 90⁰C to 95⁰C 95⁰C to 100⁰C None 10. The coefficient of curvature for well graded soil lies between 1 to 2 1 to 3 1 to 5 5 to 7 None 11. For cohesive soil, with increasing compactive effort, the optimum moisture content increases decreases remains constant zero None 12. For standard compaction test done on soil, the mass of hammer and drop of the hammer are 2.60 kg and 310 mm 2.60 kg and 450 mm 5.40 kg and 450 mm 4.80 kg and 310 mm None 13. Quick sand is a type of sand flow condition occuring in cohesive soil flow condition occuring in cohesionless soil All of the above None 14. Unit of coefficient of permeability in SI system is m/s^2 m^3/s m/s m^2/s None 15. For a granular soil, with increasing void ratio, the critical hydraulic gradient decreases increases remains constant zero None 16. The rate of consolidation increases with decrease in temperature increases with increase in temperature is independent of temperature All the above None 17. The unit of coefficient of consolidation is gm/cm^2/sec gm-cm/sec cm^2/sec cm^3/sec None 18. Vane shear test is used to find out shear strength of sandy soil gravelly soil clayey soil All options are correct None 19.
