Correct

Incorrect

103.

A curve whose radius gradually changes from an infinite value to a finite value or vice-versa for the purpose of giving easy change of direction of a road, is called a

A.	circular curve	B.	transition curve
C.	simple curve	D.	compound curve

104.

105.

In India, a curve is expressed in terms of angle in degrees subtended to the centre by an arc of

A.	25 m	B.	30 m
C.	45 m	D.	60 m

106.

Right

Wrong

107.

A circular curve may be a vertical curve.

Yes

108.

A transition curve can not be a

A.	true spiral	B.	cubic spiral
C.	compound curve	D.	cubic parabola

109.

The main advantage of providing transition curves on highways, is

A.	to obtain transition from the tangent to the circular curve and from the obtain transition from the tangent to the circular curve and from the circular to the tangent	B.	to obtain a gradual increase of curfature from a value of zero at the tangent to a maximum at the circular curve
C.	to have a gradual increase of super-elevation from zero at the tangent to a specific maximum at the circular curve	D.	all of the above
