2 cards from this section. Quick, good the night before a test.
Define the term 'radius' in the context of a circular curve.
Think about the distance from the center to the edge.
What does the degree of curvature measure?
Recall how angles are used to indicate the sharpness of turns.
What is the radius of a circular curve?
Think about the circular nature of the definition.
The degree of curve indicates what?
Reflect on how sharpness can be measured quantitatively.
A circular curve needs to be designed for safer navigation with a minimum radius of 300 m for a speed of 70 km/h. Calculate its degree of curvature.
Utilize the degree calculation formula carefully.
Given two points on a curve, A(5,10) and C(10,15), calculate the curve radius step-by-step using the Euclidean distance formula.
Focus on the relationship between the coordinates and apply the distance formula correctly.
