1000 MCQ Question Answer For Civil Engineering Competitive Exam

1000 Objective Types MCQ Question Answer For Civil Engineering Competitive Exam

Following are the 1000 important MCQ points for civil engineering competitive exam:

1. When the consistency index is less than 50 soil is soft.

2. When consistency is greater than 100 soil is very stiff.

3.  When particle size decrease, WL(Liquid Limit), WP(Plastic Limit), IP(Plasticity Index) increases.

4. Shear strength of soil at liquid limit is about 2.7Kn/m2.

5. When silt is added to clay, WL(Liquid Limit), WP(Plastic Limit) and IP(Plasticity Index) decrease.

6. Sedimentation analysis is based on Stoke's Law in which the terminal velocity of the particle is found out.

7. Sedimentation analysis can be done either by the pipette method or hydrometer method.

8. The specific gravity of solids(G) is measured at 27°C.

9. The specific gravity of solids(G) is usually taken as 2.65.

10. Alluvial soil is formed by river transportation.

11. Black soil is formed by chemical weathering.

12. Laterite soil is formed by leaching.

13. Types of transported soil and their agents:

  • Alluvial ⇾ River.
  • Marine ⇾ Ocean.
  • Lacustrine ⇾ Lake.
  • Aeolian ⇾ Wind.
  • Till ⇾ Melting of Glacier.
  • Drift ⇾ Glacier.
  • Colluvial(Talus) ⇾ Gravitation.
14. Soil types base on the soil grain size:
  • Clay ⇾ Less than 0.002mm.
  • Silt ⇾ 0.002 - 0.075mm.
  • Sand ⇾ 0.075 - 4.75mm.
  • Gravel ⇾ 4.75 - 80mm.

15. Flow net is a combination of flow lines and equipotential lines.

16. Space between two adjacent flow lines is known as a flow path or flow channel.

17. Flow lines and equipotential lines are perpendicular to each other.

18. Two flow lines never cross each other.

19. Two equipotential lines never cross each other.

20. Drop in total head between adjacent equipotential lines is the same.

21. Quick-sand is not a type of sand.

22. Quick-sand is a phenomenon that occurs on sand and other cohesionless soil.

23. The quick-sand condition occurs only in cohesionless soil( silt and fine sands).

24. Boussinesq's equation is used mainly for the shallow foundation.

25. The floor area is the plinth area less the area of the wall.

26. Vertical circulation area includes the area of staircases, lift and the space required for the vertical movement.

27. Vertical circulation area is kept within 4% to 5% of the whole area of the building.

28. An ideal fluid does not have surface tension and viscosity.

29. Ideal fluid is incompressible( Bulk modules =∞)

30. An ideal fluid does not exist in a practical situation.

31. At higher temperature, chances of cavitation are more.

32. If the temperature is 100℃, the vapour pressure of water becomes 1 atm. i.e., becomes equal to atmospheric pressure, thus boiling start.

33. If density does not change with pressure, so the fluid is incompressible.

34. In the case of liquid, the effect of compressibility is neglected, in some case like hammer pressure condition, compressibility can be taken account.

35. Bulk density of aggregate is generally expressed as kg/litre.
