Q1. A column of size 450 mm × 600 mm has unsupported length of 3.0 m and is braced against side
sway in both directions. According to IS 456:2000, the minimum eccentricities (in mm) with
respect to major and minor principle axes are
Answer : Option B
Explaination / Solution:
Q2. A venturimeter having a throat diameter of 0.1 m is used to estimate the flow rate of a
horizontal pipe having a diameter of 0.2 m. For an observed pressure difference of 2 m of
water head and coefficient of discharge equal to unity, assuming that the energy losses are
negligible, the flow rate (in m3 /s) through the pipe is approximately equal to
Answer : Option C
Explaination / Solution:
Q3. A soil is composed of solid spherical grains of identical specific gravity and diameter between 0.075mm and 0.0075mm. If the terminal velocity of the largest particle falling through water without flocculation is 0.5mm/s, that for the smallest particle would be
Answer : Option A
Explaination / Solution:
No Explaination.
Q4. Which one of the following statements is true for all real symmetric matrices?

Eigen values of a real symmetric matrix are all real
Q5. The number of independent elastic constants for a linear elastic isotropic and
homogeneous material is
Answer : Option C
Explaination / Solution:
No Explaination.
Q6. Curvature correction to a staff reading in a differential leveling survey is
Answer : Option A
Explaination / Solution:
No Explaination.
Q7. In quadrantal bearing system, bearing of a line varies from
Answer : Option C

No Explaination.
Q8. A guided support as shown in the figure below is represented by three springs (horizontal, vertical
and rotational) with stiffness kx, ky and kθ respectively. The limiting values of kx, ky and kθ are
Answer : Option A
Explaination / Solution:
As rotation and horizontal deflection in zero as per given figure. Therefore its stiffness is '∞' as deflection = 0. stiffness= Force/deflection and stiffness is zero in y direction
Q9. An automobile with projected area 2.6 m2 is running on a road with a speed of
120 km per hour. The mass density and the kinematic viscosity of air are 1.2
kg/m3 and 1.5 × 10-5 m2/s, respectively. The drag coefficient is 0.30.
The drag force on the automobile is
Answer : Option D
Explaination / Solution:
No Explaination.
Q10. With reference to a standard Cartesian (x, y) plane, the parabolic velocity distribution profile
of fully developed laminar flow in x-direction between two parallel, stationary and identical
plates that are separated by distance, h, is given by the expression
In this equation, the y = 0 axis lies equidistant between the plates at a distance h/2 from the
two plates, p is the pressure variable and µ is the dynamic viscosity term. The maximum and
average velocities are, respectively
Answer : Option A
Explaination / Solution:
