A vehicle while passing from a straight to a curved path, is under the infludnce of the weight of the vehicle and the centrifugal force.

True

False

62.

The inward tilt given to the cross-section of the road surface, throughout the length of the horizontal curve, is known as

A.	super-elevation	B.	cant
C.	banking	D.	all of these

63.

The raising of outer edge of the road above the inner edge is known as

A.	super-elevation	B.	cant
C.	banking	D.	all of these

64.

Super-elevation is expressed as

A.	the difference of heights of two edges of the carriage-way to the width of the carriage-way	B.	the difference of radii of curves
C.	the difference of the road gradients	D.	none of the above

65.

Super-elevation should not be

less

66.

Greater the super-elevation, more will be convenience to the slow moving traffic.

Right

Wrong

67.

The main advantage of providing super-elevation is

A.	to decrease the intensity of stresses on the foundation	B.	to increase the stability of the fast moving vehicles, when they negotiate a horizontal curve
C.	to achieve higher speed of vehicles	D.	all of the above

68.

In the absence of super-elevation on road along curves, pot holes are likely to occur at the

A.	centre	B.	outer edge
C.	inner edge

69.

To prevent the overturning of a bullock cart on curves, the maximum value of super-elevation as prescribed by the Indian Roads Congress is

A.	1 in 5	B.	1 in 10
C.	1 in 15	D.	1 in 20

70.

The super-elevation is

A.	directly proportional to the velocity of vehicles	B.	inversely proportional to the velocity of vehicles
C.	directly proportional to the width of pavement	D.	inversely proportional to the width of pavement
