1 / 10

The points controlling the alignment of high ways are known as

2 / 10

The longitudinal space separating dual carriage ways is known as

3 / 10

Central road fund was created in the year

4 / 10

A road 10 m wide is to deflect through and angle of 65° with the centreline radius 350 m. A transition curve is to be used at each end of a circular curve of such a length that the rate of gain of radial acceleration 0.4 m3/s, when speed is 60 km/h. Find the shift of the transition curve

5 / 10

The centrifugal ratio of a vehicle is 0.25, width of vehicle is 2.4 m, height of vehicle to its CG is 4.2 m, lateral friction is 0.15, assuming no super-elevation, then

6 / 10

A summit curve is formed at the intersection of 3% upgrade and 5% downgrade. What is the length of the summit curve in order to provide a stopping distance of 128 m is

7 / 10

A circular curve of radius 300 m, coefficient of lateral friction of 0.15 and the design speed is 40 km/h. The
super-elevation at which equal pressure is distributed on inner and outer wheel would be

8 / 10

The design speed of a road is 40 km/h and the radius of curve is 200 m. Then find the length of transition curve for the road of plain and rolling terrain

9 / 10

The turning angle of the curve is 30° and tractive force on the vehicle is 300 N. Then the loss of tractive force due to turning of vehicle in horizontal curve is

10 / 10

A test car of mass 1400 N is travelling at a speed of 85 km/h, when it is suddenly braked the wheels. The average vehicles comes to a stop in a distance of 50 m. Skid resisting force is
