Answer / itika chaudhary

Density of concrete is 2240-2400 kg/m3.
Density of steel is 7860 kg/m3.
The Pycnometer can be used for determination of the specific gravity of solid particles of both fine grained and coarse grained soils.
As the moisture content of a fixed weight of sand increases, the volume also
increases--up to a point. This is known as bulking of sand.
An under-reinforced beam is one in which the tension capacity of the tensile reinforcement is smaller than the combined compression capacity of the concrete and the compression steel.
An over-reinforced beam is one in which the tension capacity of the tension steel is greater than the combined compression capacity of the concrete and the compression steel.
A balance section is one in which the concrete crushing and steel yielding take place at the same time.

Answer / suresh bariya

Density of Concrete 2500 Kg /M3
Density of Steel 7850 Kg /M3
It is the phenomena of the increase in the valume of sand
due to water on the surface of sand is called Bulking of
sand.

asubmerged weir is one in which the water level on the down stream side of the weir is just at the crest level below the crest level above the crest level at stamp elevation as water surface on upstream
