A compression member having gross effective cross-sectional areas of 1500 mm² and 1250 mm², respectively. If the compressive stress is 150 MPa, the design compressive strength of the column will be:

A grit chamber of dimension 12mx 1.5 m x 0.8 m liquid depth has a flow of 720 m³/hour. The surface loading rate and detention time of the grit chamber would be respectively:

If the dynamic viscosity of the fluid shown in the diagram is 0.001 N.s/m², what is the shear stress 30 cm from the wall?

A retaining wall retains a sand strata with ϕ = 30° up to its top. If a uniform surcharge of 12 t/m² is subsequently put on the sand strata, then the increase in the lateral earth pressure intensity on the retaining wall will be

For a catchment area of 120 km², the equilibrium discharge in m³/hour of an S-curve obtained by the summation of 6 hour unit hydrograph is

A reinforced cement concrete beam section has a size of 300 mm width and 400 mm effective depth, the grade of concrete used is M20 and grade of steel is Fe 415. If the ultimate bending moment of 150 kN-m acts at the section, the beam has to be designed as

A steel bar ABC of uniform cross-section 100 mm² is suspended vertically and loaded as shown in the figure. If the lower end of bar C does not move when loads are applied (neglect self-weight), then the value of force P is (E_S = 200 kN/mm²)

In an area of heavy rainfall, a state highway of high-type bituminous surface with four lanes (14.0 m wide) is to be constructed. What will be the height of the crown of the road relative to the edges for a composite camber (i.e. middle half as parabolic and rest as straight lines)?
