SOLUTION
S1. Ans.(b)
Sol.
| Concrete Grade | Type of concrete |
| M10 – M20 | Ordinary |
| M25 – M55 | Standard |
| M60 – M80 | High strength |
S2. Ans.(d)
Sol. Density of mild steel is about 7850 kg/m³. hence One cubic meter of mild steel weights about 7850 kg.
S3. Ans.(c)
Sol. according to WHO, the permissible limit of chloride content in drinking water is 250 mg/l.
S4. Ans.(d)
Sol. There are some forms of precipitation-
- Rainfall
- Drizzle
- Glaze
- Snow
- Sleet
- Hails
S5. Ans.(c)
Sol. Distance between mid point of curve (C) to mid point of long chord (D) is known as mid ordinate (versed sine) of the Curve.
▭(CD=R-R cos〖∆/2 〗 )
S6. Ans.(c)
Sol. Spacing between lateral ties –
Maximum spacing should not be greater than.
- 16×minimum diameter of bar
- Least lateral dimension
- 300 mm.
S7. Ans.(c)
Sol. Consistency limit is measured by Casagrande’s apparatus.
S8. Ans.(c)
Sol. There are some assumptions for Bernoulli’s theorem
(1) The flow is steady.
(2) The flow is incompressible.
(3) The flow is frictionless
(4) The flow continuous
(5) The flow should be irrotational or rotational along streamline.
S9. Ans.(a)
Sol. The allowable stress in a long column can be increased by increasing it’s radius of gyration and radius of gyration depends on moment of inertia.
R=√(I/A)
R- radius of gyration
I- Moment of Inertia
S10. Ans.(a)
Sol. The penetration test on bitumen is used for determining the Grade of bitumen.
