(b) Kolkata
(c) New Delhi
(d) Mumbai

Q10. For a comfortable travel on Highways, the centrifugal ratio should not exceed
(a) 0.1
(b) 0.15

SOLUTION

S1. Ans.(d)
Sol. Metamorphic rocks are formed by the change in character of the original rocks when they are subjected to great heat and pressure.

S2. Ans.(c)
Sol. the permissible limit of iron in drinking water as per IS 10500:2012 is 0.3 mg/l.

S3. Ans.(c)
Sol. the formwork shall be measured in square meter.

S4. Ans.(c)
Sol. If stream function exists then it will automatically satisfy the continuity equation otherwise flow will not exist. If stream function also satisfies the Laplace equation then the flow is irrational.

S5. Ans.(d)
Sol. On the basis of alignment, the classification of canal is as follows-
Ridge canal or watershed canal
Contour canal
Side slope canal

S6. Ans.(b)
Sol. if ‘d’ is diameter of steel bar then diameter of hook is ‘4d’.

S7. Ans.(c)
Sol. water content (w) = 200%
G= 2.6
Void Ratio (e) =?
→ soil is fully saturated (S = 1)
Se = WG
1×e = 2×2.6
▭(e=5.2)

S8. Ans.(d)
Sol. According to hooks law strain is directly proportional to stress within proportional limit

S9. Ans.(d)
Sol. the mean sea level is adopted by survey of India is located at Mumbai, but earlier the reference of mean sea level (M.S.L) was located in Karachi (Pakistan).

S10. Ans.(d)
Sol. For a comfortable travel on Highways, the centrifugal ratio should not exceed 0.25.
