What is the ideal banking angle for a gentle turn of 1.20 km radius on a highway with a 105 km/h speed limit (about 65 mi/h), assuming everyone travels at the limit?

Solution 25PE :

Step 1 of 3:-

The radius of the curve is, .

The speed is, .

While moving through the curve, the normal component which is the weight of the vehicle is,

-------------------(1)

And --------------------(2) (the centripetal force).

Here is the bending angle which has to be determined.

Step 2 of 3:-

From the above two equations, we can get,

--------------------------(3)
