Question 1.
What is the ruling minimum radius formula?
Show hintHide hint
Remember the variables involved in the formula.
Question 2.
Why is a larger curve radius often safer?
Show hintHide hint
Think about the forces acting on a vehicle in a curve.
3Question 3.
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)
Show hintHide hint
Keep in mind how each variable affects the outcome.
4Question 4.
True or False: A larger radius can lead to higher maximum comfortable speeds.
- True
- False
Show hintHide hint
Consider the relationship between radius and speed.
Question 5.
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.
Show hintHide hint
Use the ruling minimum radius formula and convert km/h to m/s.
Question 6.
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?
Show hintHide hint
Remember to check if the calculated radius aligns with the design speed in practical scenarios.
