In a beam of 300 mm wide and 500 mm effective depth, the value of the design shearing force at the critical section is 300 kN. The permissible shear stress in concrete is 0.4 N/mm2 depending on the percentage of steel content. The shear reinforcement will be designed for a shear force of ____ kN

Calculate the spacing between contraction joints by using the following data:

Width of slab = 4.52 m

The thickness of the slab = 25 cm

Coefficient of friction = 1.5

Allowable tensile stress in steel = 1400  kg/cm²

Diameter of bar = 12 mm

Spacing between the bar = 300 mm

Take γ_c = 2400 kg/m³

Spot speed studies were conducted on a certain stretch of a highway and consolidated data collected are given below:

Determine the upper and lower values of speed limits for the regulation of mixed traffic flow.

The width of the elementary gravity dam as shown below is -

Take specific gravity of dam material 2.2 and seepage coefficient at the base C = 0.8

A city with a population of 4 lakh generates municipal solid waste(MSW) at the rate of 160 g/capita/day. The MSW will be decomposed by incineration method which produces 9 kg of ashes per 50 kg of MSW. These ashes will be further used in the cement industry. The amount of Portland cement that can be produced per day if 1kg of cement requires 200 gm of ash.

The evaluation of the definite integral  by using Simpson’s 1/3^rd (one –third) rule with step size h = 0.6 yields

The stress state at a point in a material under plane stress condition is equi-biaxial tension with a magnitude of 10 MPa. If one unit on the σ - τ plane is 1 MPa, the Mohr’s circle representation of the state-of-stress is given by

A problem in Mathematics is given to three students A, B and C. The probability of A solving the problem is 1/2 and B not solving is 1/4. The whole probability of the problem being solved is 63/64. What is the probability of solving it by C?

Which of the following cement is recommended mostly in 

(i) Concrete to be used in marine condition.

(ii) Concrete to be used in the construction of sewage treatment works.

(iii) Concrete used for fabrication of pipes which are likely to be buried in marshy region
