The radius of curvature for on unbanked curve marked
Answer to Problem 20P
Solution:
28.12m
Explanation of Solution
Given:
The speed limit for an unbanked curve
Coefficient of static friction between rubbers on wet concrete
Formula used:
The centripetal force needed to move on the unbanked road
Where m: a mass of the vehicle
v :speed of the vehicle
r : radius of an unbanked road
Calculation:
Conclusion:
Hence,the radius of the unbanked curve must be greater than or equal to
