Transportation Engineering || Test 8

1 / 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

2 / 10

The factors affecting the highway alignment are

3 / 10

An ascending gradient of 1 in 45 meets a descending gradient of 1 in 60. A summit curve has to be designed for design speed of 80 km/h so as to provide a safe overtaking sight distance of 230 m. Estimate the length of the summit curve.

4 / 10

A parabolic curve is used to connect a 4% upgrade with a 2% down grade as shown in fig. The highest point on the summit is at a distance of (measured horizontally from the first tangent point—FTP) 5 / 10

The important factor considered in the design of summit curves on highway is

6 / 10

The length of summit curve on a two lane two way highway depends upon

7 / 10

The ideal form of the curve for the summit curve is

8 / 10

Determine the extra width of pavement and the length of transition curve needed on a horizontal alignment of radius 225 m for the two lane road, with a design speed of 80 km/h. Assume the wheel base of design vehicle as 6 m

9 / 10

A vehicle is manouvering a horizontal curve of radius R with super-elevation q°. Find the value of the maximum speed beyond which the vehicle would overturn outward, if R = 250 m, q = 5°, f = 0.15, h = 1 m, b = 0.75 m in (km/h) 10 / 10

There is a horizontal curve of radius 360 m and length 180 m. Calculate the clearance required from the centre line on the inner side of the curve, so as to provide an overtaking sight distance of 250 m.
