Question 1

What is the formula for calculating the ruling minimum radius?

  • R = (v^2) / (g(e + f))
  • R = (g(e + f)) / (v^2)
  • R = v^2 * g * (e + f)

💡 Hint: Keep in mind how each variable affects the outcome.

Question 2

True or False: A larger radius can lead to higher maximum comfortable speeds.

  • True
  • False

💡 Hint: Consider the relationship between radius and speed.

Challenge Problems

Push your limits with challenges.

Question 1

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.

Question 2

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.
