DMRC JE CIVIL 2014 PAPER 1. Effective size = D10 2. Commonly used coagulant = Alum 3. When road is raised towards outward = super elevation 4. Purlin is = compression member 5. Ellective length of fillet weld = total length – 2 x weld size = 100 – 2 x 4 = 92 6. In a S.S beam if depth is increased by 2 times, deflection will b multiplied by a factor = ½ 7. In a cantilever beam if width is doubled , then deflection will be = ½ 8. Main r/f are always provided in cantilever beam at = top 9. Max. B.M. in S.S beam carrying u.d.l.of 500kn/m and span of 4 m = 2000 kn 10. Slederness ratio of steel column = effective length / radius of gyration 11. Reynold’s no. Is ration of = inertia force / viscous force 12. A body is in a state of equilibrium when = meta centre is above centre of gravity 13. A point in a body where total pressure act is called = centre of pressure 14. A R.C.C. beam was contructed at temp of 42 degree C, stress in concrete during winter when temp is 5 degree C = tensile 15. To increase intial setting time of cement = gypsum is used 16. Initial setting time of opc = 30 min 17. To determine hardness = impact test 18. Min. Cover in slab = 15mm or dia. Of bar 19. Test to determine workability of concrete having very low w/c ratio = comaction factor test( vee- bee test was not in the list) 20. At Point of contraflexure = B.M. is zero 21. Modular ratio = 280/ 3 sigma cbc 22. Which Mix is not allowed as pe IS 456 = M90 23. A RCC beam have equal resistance to = tension, compression and shear 24. Hydrdyanamic pressure in retaining wall = i marked 3h/ 4 pie but ithink galat hai 25. Water pressure depend on = wh = depth 26. BOD of water is = strength of pollution due to bio degradable organic waste 27. If B.S. is more than F.S. than = Back staff is at lower level 28. Min. Super elevation on curves = 4 % 29. No. Of standard brick in 1 cu.m. = 500 30. Le-chatelier’s device is used to determine = soundness of cement 31. Material of cement that provide adhesive value = lime 32. Silt in dam is considered as = cohesionless soil 33. One question was of arch 34. Fineness of sand lies in = 3.0 35. Bricks are burnt at 900- 1200 degree C 36. Instrument used in plane table to measure horizontal and vertical distance without the help of chain= 37. Bark = outermost layer of tree 38. Backwashing arrangement is provided in = rapid sand filter 39. Method to calculate fire demand = 40. Rapid hardening cement is obtained by = burning at higher temperature 41. If the ratio of length to depth is less than 2, = deep beam 42. One question was also like dis in which answer was = all 43. Cowl is used at = 44. A 45 degree angle can b formed by = optical square 45. Disinfection is used to remove = bacteria 46. M = 2 j -3 47. Most common cause of acidity = CO2 48. Tie bar is used at = longitudinal joints 49. Pelton wheel = tangential flow impulse turbine. 50. Determine force in triangular frame carrying 5 kn compressive force at top, find force in member CD=
