Question 2

What will be the immediate settlement of a column footing 1.5 m diameter that is constructed upon an unsaturated clay layer, given that total load carried by the column is 225 KN: modulus of elasticity of soil= 1000 KPa; Poisson’s ratio=0.25.

Assume the footing to be rigid and influence factor If as 0.8

Question 3

What will be the maximum upper limit of BOD of a glucose solution of concentration 300 mg/l?

Question 4

A slab of depth 200 mm is designed as per IS: 456. The bond stress is 0.87 MPa for M20 grade of concrete and Fe415 grade of steel. The development length in tension using 20 mm diameter longitudinal bars is

Question 5

The rolled steel I – sections are most commonly used as beams because these provide:

1- large moment of inertia with less cross-sectional area

2- greater lateral stability

Question 6
