Question

A vehicle is travelling with a speed of 80 kmph on a 4 lane highway. If the width of each lane is 3.5 m and the highway has an horizontal curve of radius 500 m, then the centrifugal ratio is

• A. 0.130
• B. 1.30
• C. 0.1
• D. 0.056

Answer 1

The correct option is C 0.1

Centrifugal ratio = $\frac{V^2}{127R}=\frac{{80}^2}{127\times 500}=0.1$
