Question 4

At what distance after the load had just crosses a section the maximum bending moment at the left quarter of a simple beam due to crossing of UDL of length shorter by span in the direction left to right.

Question 5

A core cutter 13 cm in height and 10 cm in diameter, and having a mass of 1078 g when empty, is used to determine the in-situ density of an embankment. The mass of the core cutter full of soil is 2968 g. If the water content of the soil is 8%, then the in-situ dry density is _______ g/cm³.
[Take Specific gravity of soil particles = 2.65]

Question 6

Question 7

If the expected time for completion of a project is 10 days with a standard deviation of 2 days, the expected time of completion of the project with 99.9% probability is

Question 8

A concrete column carries an axial load of 500 kN and bending moment of 75 kNm at its base. An isolated footing of size 3 m x 5 m side along the plane of the bending moment, is provided under the column. Centres of column and footing coincide. The ratio of maximum and minimum pressure on soil under the footing is _____.

Question 9

A water supply board is responsible for treating 1500 m3/day of water. A settling column analysis indicates that an overflow rate of 20 m/day will produce satisfactory removal for a depth of 3.1 m. It is decided to have two circular settling tanks in parallel. The required diameter (expressed in m) of the settling tanks is ___________.

Question 10

The normal annual rainfall at station I, II, III, and IV in a basin are 155, 150, 150 and 105 cm respectively. In the year 2000, stations I, II and III received annual rainfalls of 156, 140 and 104 cm respectively. Estimated value of rainfall (in cm) at station IV during the year 2000 is
