Curves

The radius of a one degree curve is

• 1760
• 1719
• 176
• 17.19

If the angle of intersection of a curve is ø then deflection angle will be

• 180+ø
• 180-ø
• 90-ø
• 90+ø

What is the maximum super elevation provided for metre gauge?

• 90 mm
• 90 cm
• 90 m
• 90 km

In case of vertical parabolic curves, the rate of change of gradient is

• always negative
• always positive
• zero
• constant

Where did sub chords generally occurred during setting of the curve.

• At beginning and end of the curve
• At middle portion
• Any where on the curve
• Only at end of the curve

The angle of intersection of a curve is the angle between

• Back tangent and forward tangent
• Back tangent and long chord
• Back tangent and Fore sight
• Fore sight and back sight

A straight line joining the ends of an arc is called :

• Chord
• Segment
• Quadrant
• Sector

The type of curve generally provided on highway is

• Circular curve
• Transition curve
• Vertical curve
• All of these

A curve whose radius gradually changes from an infinite value to a finite value or vice-versa is called

• circular curve
• transition curve
• simple curve
• compound curve

The ideal transition curve is called a

• Clothoid
• cubic spiral
• cubic parabola
• hyperbola
