SOLUTIONS

S1. Ans.(d)
Sol. As per IS, the concrete should be cured under a humidity of 90%.

S2. Ans.(b)
Sol. The woodworks should be measured nearest up to 0.002m or 2 mm.

S3. Ans.(c)
Sol. if the pH is more than 8.3 then phenolphthalein indicator turns water into pink color. phenolphthalein is a basic indicator.

S4. Ans.(a)
Sol. Peak flood discharge given by dicken’s formula-
Q=CA^(3/4)
Where Q= Peak flood discharge (m³/sec)
C= Dicken’s coefficient
A= Area in km²

S5. Ans.(a)
Sol. contour interval is the vertical distance two consecutive contours. contour interval depends on scale of the map, nature of ground, purpose of map etc. if scale is small then contour interval large.

S6. Ans.(a)
Sol. Malleability is the property of material allows it to expand in all direction without rupture.

S7. Ans.(d)
Sol. In fluid dynamics, the drag coefficient has no dimensions. It is a dimensionless quantity. Drag coefficient is used to quantify the resistance of an object in a fluid environment. It is mainly used in air and water.
S8. Ans(a)
Sol. When tension member is subjected to heavy load, the number of bolts or length of welds required for making connection becomes large, it results in uneconomical size of gusset plates. In such situations, additional short angles called lug angles may be used to reduce joint length and shear lag.
S9. Ans(c)
Sol. the summit curve is provided when an up gradient of a highway meets a downgrade.

S10. Ans(c)
