SOLUTION

 

S1. Ans.(a)

Sol. The ratio of weight of rail in tones to the locomotive axle load in tonnes is 1:510 in India.

 

S2. Ans.(b)

Sol. Distemper is used to coat interior surface not exposed to weather. It is made with base as white chalk and thinner as water.

 

S3. Ans.(d)

Sol. Hydrology is a branch of science which deals with circulation, distribution and movement of water on and below the earth surface and its atmosphere.

 

S4. Ans.(d)

Sol. Torsion resisting capacity of a given reinforced concrete section increase with increases in stirrups and longitudinal steel.

 

S5. Ans.(a)

Sol. primary consolidation – due to expulsion of pore water

Secondary consolidation – Due to plastic rearrangement of soil solid.

 

S6. Ans.(b)

Sol. Infinite planes passes through a single point. Out of infinite planes three planes are mutually perpendicular to each other and having zero shear stress, that planes are called principal plane.

 

S7. Ans.(c)

Sol. the surface parallel to earth surface in known as level surface and tangent to any point of level surface is horizontal surface.

 

S8. Ans.(a)

Sol. Chemical oxygen demand indication the amount of oxygen required to carry out the decomposition of both biodegradable or non-biodegradable organic matter present in the system.

 

S9. Ans.(c)

Sol. Unit weight of R.C.C. = 2500 kg/m³

Unit weight of plain cement concrete = 2400 kg/

 

S10. Ans.(a)

Sol. The property at which it’s all energy measured at its static condition. When a fluid having zero velocity then it is the condition of stagnation. then its K.E. is zero and K.E. is function of absolute temp. so at zero absolute temp. property of fluid is known as stagnation property.
