In the siphon shown in the figure below,assuming ideal flow, pressure PB
-
Solution
As PA= PC both a have atmospheric pressure and keeping other factors of energy constant, as liquid is flowing from B to C, PB < PC
Hence PB < PA
If the displacement of a plotted point perpendicular to the ray was 25 cm, the scale at which the error centering becomes significant is, taking the plotting accuracy as 0.025 cm is
-
Solution
\(\frac{0.025}{25}\Rightarrow \frac{1}{1000}\)
The stress distribution at a depth beneath a loaded area is determined using Newmark’s influence chart which indicates a influence value of 0.005. The no. of segments covered in the loaded area in the chart is 10 and intensity of loading on the area is 10t /m2. The intensity of stress distribution at the depth is
-
Solution
\(\sigma _{2}=I_{f}qN\)
= 0.005 × 10 × 10
= 0.5 t/m2.
If the difference in elevation of an edge of the pavement 9m wide and its crown is 15 cm, the camber of the pavement,is _____
A column (300 × 300) mm, length 2.5 m is fixed atone end and restrained against rotation. While the other end is effectively restrained against rotation but not braced against sides way.The minimum eccentricity for which column will be designed?
-
Solution
\(_{max}^{e_{min}}=\left\{\begin{matrix} \frac{L_{eff}}{500}+\frac{D}{30} & \\ 20\, mm & \end{matrix}\right.\)
=\(\left\{\begin{matrix} \frac{2.5\times 1.2}{500}+\frac{300}{30}=b+10=16mm & \\ 20\, mm & \end{matrix}\right.\)
= 20 mm
With referance to the buss given below, which of the statement is correct.
-
Solution
The given truss on inclined loading condition will become unstable, as it will have horizontal component which will cause unstability and truss CDEFG will move in horizontal direction.
While this truss will be stable where loading is vertical.Hence, stability depends on loading conditions i.e. option (c)

Which of there statements are correct?
The position of a point can belocked in GPS on receiving signals from at least.
The degree of static indeterminacy of Ashok Chakra is ____(There are 24 straight lines)
-
Solution
No. of cuts will be 24
Indeterminacy with respect to each cut = 24 × 3 = 72
A cylindrical fall, popularly known as Syphon well drop, is suitable and economical for
-
Solution
If the fall is greater than 1.8 m and discharge is greater than 0.29 m3/sec, this type of downstream well is necessary
