is
Answer : Option A
Explaination / Solution:
No Explaination.
Q2. The chainage of the intersection point of two straights is 1585.60 m and the angle of
intersection is 140o . If the radius of a circular curve is 600.00 m, the tangent distance (in m)
and length of the curve (in m), respectively are
Answer : Option C
Explaination / Solution:
Length of curve, L = (π/180)× ∆×R
= (π/180)×40×600 = 418.88m
Tangent distance, T = R tan(∆/2)
= 600tan(40/2) = 218.38m
Q3. A 1 hour rainfall of 10 cm has return period of 50 year. The probability that
1 hour of rainfall 10 cm or more will occur in each of two successive years is
Answer : Option D
Explaination / Solution:
Return period of rainfall, T = 50 years
Probability of occurrence once in 50 years, p = 1/50 = 0.02
Probability of occurrence in each of 2 successive years = p2 = (0.02)2 = 0.0004
Q4. As per IRC : 67 : 2001, a traffic sign indicating the Speed Limit on a road should
be of
Answer : Option A
Explaination / Solution:
No Explaination.
Q5. A rigid member ACB is shown in the figure. The member is supported at A and B by
pinned and guided roller supports, respectively. A force P acts at C as shown. Let RAh and RBh be the horizontal reactions at supports A and B, respectively, and RAv be the
vertical reaction at support A. Self- weight of the member may be ignored. Which one of the following sets gives the correct magnitudes of RAv, RBh and RAh?
Answer : Option D
Explaination / Solution:
No Explaination.
Q6. Ultimate BOD of a river water sample is 20 mg/L. BOD rate constant (natural log) is 0.15 day-1.
The respective values of BOD (in %) exerted and remaining after 7 days are:
Answer : Option C
Explaination / Solution:
Q7. The clay mineral primarily governing the swelling behavior of Black Cotton soil is
Answer : Option D
Explaination / Solution:
No Explaination.
Q8. The equation 
has
has
Answer : Option D
Explaination / Solution:
No Explaination.
Q9. The latitude and departure of a line AB are +78m and −45.1m respectively. The
whole circle bearing of the line AB is
Answer : Option D
Explaination / Solution:
Since the latitude of line is positive and departure is negative, the line lies in
Fourth quadrant.
l cos θ = 78; l sin θ = -45.1
tanθ = -0.578
θ = -30o
WCB of AB = 360o-30o = 330o
Q10. An isohyet is a line joining points of
Answer : Option C
Explaination / Solution:
No Explaination.
