Chapter 25, Problem 25.1P
To determine
Advantage of using a parabola in the vertical curve design
Expert Solution & Answer
Explanation of Solution
The vertical curve should provide smooth transitions between two set of grades. The ideal applied for vertical curves is parabola because it provides constant rate of change of grade for highways and railroads.
Conclusion:
The main advantage of using parabola because it provides smooth transition of curve.

They are designed to get you out of your classroom or office and develop the skills of designing experiments and collecting data, and then performing calculations, evaluating the results, and communicating your findings. Labs are more than just number crunching - they are about reflecting on what is both practical and technically sound engineering problem-solving. For each problem below, address the scenario presented and develop engineering solutions. Communicate your results using drawings, pictures, and discussion, supported by calculations developed using the Microsoft Equation Editor or similar tool.
