The design speed is normally ______ for terrains with steep slopes
D. Can not say
Explanation: The design speed is normally reduced for terrains with steep slopes
Centrifugal force depends on ___________ of the horizontal curve.
C. Both A and B
D. None of the above
Explanation: Centrifugal force depends on speed and radius of the horizontal curve and is counteracted to a certain extent by transverse friction between the tyre and pavement surface.
___________ is the transverse slope provided at horizontal curve to counteract the centrifugal force.
D. All of the above
Explanation: Super-elevation or cant or banking is the transverse slope provided at horizontal curve to counteract the centrifugal force, by raising the outer edge of the pavement with respect to the inner edge, throughout the length of the horizontal curve.
The degree if curve is central angle subtended by an arc of length is?
A. 30 m
B. 35 m
C. 40 m
D. 45 m
Explanation: The relation between degree and radius of circular curve is RDπ/180=30.
Does design speed does not depends on the type of the road?
C. Can be true or false
D. Can not say
Explanation: False, design speed also depends on the type of the road.
The ratio between centrifugal force and weight of the vehicle is called ___________
A. Impact ratio
B. Centrifugal factor
C. Impact factor
D. Centrifugal impulse
Explanation: The relationship between centrifugal force and weight of the vehicle is called impact factor or centrifugal ratio.
If the radius of a horizontal curve is 120m, then calculate the safe allowable speed.
Explanation: The safe allowable speed is Va = √(27.94R)
Va = √(27.94*120)
Va = 60kmph.
The length of wheel base usually considered in India is?
A. 6.1 m
B. 6.2 m
C. 6.3 m
D. 6.4 m
Explanation: The length of the wheel base may be assumed as 6.0m or 6.1m for vehicles if data is unknown, this value is considered for commercial vehicles.
The extra width required on two lane pavement for a radius of curve 100m as recommended by IRC is ___________
Explanation: IRC recommends a value of 0.9m for two lane pavement for radius of curve 100m, this value decreases with increase in the length of curve.
The most preferred type of transition curve by IRC for highway is ___________
B. Cubic parabola
Explanation: The most preferred type of transition curve by IRC for highway is parabola, for its ease of construction and other field work.
