Q4. The average surface area of a reservoir in the month of June is 20 km2. In the same month, the
average rate of inflow is 10 m3 /s, outflow rate is 15 m3/s, monthly rainfall is 10 cm, monthly
seepage loss is 1.8 cm and the storage change is 16 million m3

month is
Answer : Option B
Explaination / Solution:
Q5. 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:
Q6. 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
Q7. A steel member ‘M’ has reversal of stress due to live loads, whereas another member ‘N’ has
reversal of stress due to wind load. As per IS 800:2007, the maximum slenderness ratio permitted
is
Answer : Option A
Explaination / Solution:
M – due to live load
N – due to wind load
As per IS800.
M - λ - 180
N - λ - 350 M<N
