SOLUTIONS

S1. Ans.(b)
sol. Peak hour factor is expressed in percentage of AADT; it is used in the design of transportation facilities and major projects.

S2. Ans(d)

Sol. Triaxial compression test is used to find Shear strength of soil.

S3. Ans.(d)
sol. City surveying is made in connection with the construction of streets, water supply systems and sewers. A survey which deals with bodies of water for purpose of navigation, water supply, harbor works or for the determination of mean sea level is hydrographic surveying.

S4. Ans(c)

S5. Ans.(c)
sol. The slow sand filters are highly efficient in the removal of bacteria and can remove around 98-99% of bacteria present in water.

S6. Ans.(b)
sol. Over vibration may lead to a problem called segregation. The coarse aggregate is separated from the cement matrix. This leads to low strength.

S7. Ans.(c)

Sol. The number of bricks (conventional size) requires for one square meter of brick on edge soling is 54.

S8. Ans.(b)

Sol. Meyer’s formula is a empirical formula used to determine evaporation loss.

Meyer equation-

Where

E= Rate of evaporation (mm/day)

K= constant

= Saturation vapour pressure

= Actual vapour pressure

S9. Ans.(a)

Sol. Star shakes  These are the cracks in timber which extended from bark towards the sapwood. These cracks are wider at outside and narrower at inside.

S10. Ans.(d)

Sol. Rupture stress is the sudden and complete failure of a material under stress.
