- Question 9 of 15
The following statements are related to temperature stresses developed in concrete pavement slabs with free edges (without any restraint):
P. The temperature stresses will be zero during both day and night times if the pavement slab is considered weightless
Q. The temperature stresses will be compressive at the bottom of the slab during night time if the self-weight of the pavement slab is considered
R. The temperature stresses will be compressive at the bottom of the slab during day time if the self-weight of the pavement slab is considered
The TRUE statement(s) is(are)CorrectIncorrect
- Question 10 of 15
The Reduced Levels (RLs) of the points P and Q are +49.600 m and +51.870 m respectively. Distance PQ is 20 m. The distance (in m from P) at which the +51.000 m contour cuts the line PQ isCorrectIncorrect
- Question 11 of 15
A traffic office imposes on an average 5 number of penalties daily on traffic violators. Assume that the number of penalties on different days is independent and follows a Poisson distribution. The probability that there will be less than 4 penalties in a day is ___________CorrectIncorrect
- Question 12 of 15
For a beam of cross-section, width = 230 mm and effective depth = 500 mm, the number of rebars of 12 mm diameter required to satisfy minimum tension reinforcement requirement specified by IS:456-2000 (assuming grade of steel reinforcement as Fe500) is _____________CorrectIncorrect
- Question 13 of 15
In a reinforced concrete section, the stress at the extreme fibre in compression is 5.80 MPa. The depth of neutral axis in the section is 58 mm and the grade of concrete is M25. Assuming linear elastic behavior of the concrete, the effective curvature of the section (in per mm) isCorrectIncorrect
- Question 14 of 15
A horizontal jet of water with its cross-sectional area of 0.0028 m*m hits a fixed vertical plate with a velocity of 5 m/s. After impact the jet splits symmetrically in a plane parallel to the plane of the plate. The force of impact (in N) of the jet on the plate isCorrectIncorrect
- Question 15 of 15
A venturimeter, having a diameter of 7.5 cm at the throat and 15 cm at the enlarged end, is installed in a horizontal pipeline of 15 cm diameter. The pipe carries an incompressible fluid at a steady rate of 30 litres per second. The difference of pressure head measured in terms of the moving fluid in
between the enlarged and the throat of the venturimeter is observed to be 2.45 m. Taking the acceleration due to gravity as 9.81 m/s2, the coefficient of discharge of the venturimeter (correct up to two places of decimal) isCorrectIncorrect
