Given a road curve design for a maximum speed of 100 km/h, calculate the ruling minimum radius considering a superelevation of 0.07 and a friction coefficient of 0.15.
💡 Hint: Use the ruling minimum radius formula and convert km/h to m/s.
A curve has a radius of 300m, and the design speed is set to 90 km/h. What is the maximum allowable speed for a vehicle given that the coefficient of friction is 0.1 and the maximum superelevation is 0.07?
💡 Hint: Remember to check if the calculated radius aligns with the design speed in practical scenarios.
