Q1.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 DExplaination / Solution: No Explaination.
Q2.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 metric horse power required to overcome the drag force is
Answer : Option CExplaination / Solution: No Explaination.
Q4.The capacities of “ One-way 1.5 m wide sidewalk (persons per hour)” and “
One-way 2 lane urban road (PCU per hour, with no frontage access, no standing
vehicles and very little cross traffic)” are respectively
Answer : Option AExplaination / Solution: No Explaination.
Q7.A roundabout is provided with an average entry with of 8.4 m, width of weaving
section as 14 m, and length of the weaving section between channelizing islands
as 35 m. The crossing traffic and total on the weaving section are 1000 and 2000
PCU per hour respectively. The nearest rounded capacity of the roundabout ( in
PCU per hour) is
Answer : Option BExplaination / Solution: No Explaination.
Q8.The plan of a survey plotted to a scale of 10 m to 1 cm ie reduced in such a way
that a line originally 10 cm long now measures 9 cm. The area os the reduced plan
is measured as 81 cm2. The actual area (m2) of the survey is
Answer : Option AExplaination / Solution: No Explaination.
Q9.It is proposed to widen and strength and existing 2-lane NH section as a divided highway. The existing traffic in one direction is 2500 commercial vehicles (CV) per day. The construction will take 1 year. The design CBR of soil subgrade is found to be 5 per cent. Given : traffic growth rate for CV = 8 per cent, vehicle damage factor =3.5 (standard axles per CV), design life = 10 years and traffic distribution factor =0.75. The cumulative standard axles (msa) computed are
Answer : Option BExplaination / Solution: No Explaination.
