Questions
A circular curve of a highway is designed for traffic moving at 72 kmh-1. If the radius of the curved path
is 100 m, the correct angle of banking of the road should be
a
tan-125
b
tan-135
c
tan-115
d
tan-114
detailed solution
Correct option is A
Given, v=72kmh-1=72×518 ms-1=20 ms-1R = 100 m∴ θ=tan-1v2Rg=tan-1400100×10=tan-125Talk to our academic expert!
