A prismatic bar of cross-sectional area 1 mm² and E = 200 GPa is fastened between two rigid walls at A and B and are subjected to loads as shown.

The support reactions at B and A (in kN) are

A cast-in-situ bored pile 0.50 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

If staff readings taken on B and C by a tacheometer placed at A are

Calculate the sum of multiplying and additive constants of the tacheometer(in integer).

The longitudinal section of the runway provides the following data:

Calculate the effective gradient of the section.

Determine the thickness (in mm, round to next even integer) of a bearing plate at the support for ISMB 600 resting on a concrete masonry wall 250 mm thick for the following data.

Reaction = 200 kN

Grade of concrete: M20

Properties of ISMB 600 @ 1202.71 N/m are:

b_f = 210 mm, t_f = 20.8 mm, t_w = 12 mm, Radius at root = 20 mm

To control vehicular pollution from exhaust of vehicles, following is fitted:

The concentration of OH- ion in a water supply is measured as 17 mg / L at 25° C. What is the pH of the water sample?

A sub grade soil sample was tested using standard CBR apparatus and the observations are given below.

Assuming that the load-penetration curve is convex throughout, the CBR value (%) of the sample is

A cantilever beam of length L and flexural modulus EI is subjected to a point load P at the free end. The elastic strain energy stored in the beam due to bending (neglecting transverse shear) is
