Two irrigation channels A and B are designed using Lacey’s theory. If the median diameter of the silt particles are the same for both the channels, and if the discharge in channel A is 70% greater than at B, then between these two channels.

Solution
In a district where the rainfall is heavy, MDR of WBM pavement, 3 m wide is to be constructed. What should be height of crown with respect to the edges :(Range of camber, as per IRC is – 2.5% to + 3%).

Solution
A cube is subjected to equal tensile stress on all the three faces. If the yield stress of the material is σy, then based on the strain energy theorem, the maximum tensile stress will be.

Solution
The moment at the fixed end of a propped cantilever beam shown below will be ________ KNm.
-
Solution
Taking moments about B
ΣM2B= O(as B is Hinged)
(30 × 2) = RC × 1
So RC= 60 kN
New drawing F.B.D.
Hence, moment at fixed end will be 30 kNm.
Lap length in direct tension should be
-
Solution
In case of direct tension, lap length should be greater of 2Ld or 30φ.
where, Ld= development length
φ = diameter of bar.
Muller–Breslau principle is the straight application of 1.Maxwell’s reciprocal theorum 2.Flexibility method 3.Slope deflection method Which of these statements are correct.
A two–hinged semi circular arch of radius R carries a concentrated load W at shown. Then horizontal thrust is equal to KW⁄π. Value of constant K will be ______.

Solution
An ocean going ship, when on high seas is subjected to oscillatory motion both by rolling and pitching. Which of the following statements related to the metacentric height of the ship is correct.
-
Solution
If the ship is safe is rolling then it will be safe for pitching also.Hence metacentric height in case of rolling should be smaller than pitching
The flow mass curve is an integral curve of
-
Solution
The flow mass curve is a graph between cumlative runoff volume with respect to time (in days are months).
Hydrograph is a graph between discharge and time.Hence, when we add one hydrograph with another we get the flow mass curve.
A cast in situ bored pile 0.5 m diameter and 10 m deep is placed in a purely cohesive soil. If the cohesion of the soil is 4t/m2 and adhesion between the pile and the soil is half the value of cohesion,then the ultimate bearing capacity of the pile is given by
