Radius of Curve given Length of Valley Curve Solution

STEP 0: Pre-Calculation Summary

Formula Used

Radius of Curve = (Design Speed^3)/(Length of Curve*Rate of Change of Acceleration)
R = (v^3)/(L_s*C_a)
This formula uses 4 Variables

Variables Used

Radius of Curve - (Measured in Meter) - Radius of Curve typically represents the minimum radius of the curve.
Design Speed - (Measured in Meter per Second) - Design speed refers to the intended or planned operating speed for a particular section of a roadway or railway.
Length of Curve - (Measured in Meter) - Length of Curve is the distance along the road where the alignment changes from upward to downward slope, creating a valley-shaped concave.
Rate of Change of Acceleration - (Measured in Meter per Second) - Rate of Change of Acceleration refers to how quickly the acceleration of an object changes over time.

STEP 1: Convert Input(s) to Base Unit

Design Speed: 5 Meter per Second --> 5 Meter per Second No Conversion Required
Length of Curve: 12.71876 Meter --> 12.71876 Meter No Conversion Required
Rate of Change of Acceleration: 4.2 Meter per Second --> 4.2 Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

R = (v^3)/(L_s*C_a) --> (5^3)/(12.71876*4.2)

Evaluating ... ...

R = 2.34000050019851

STEP 3: Convert Result to Output's Unit

2.34000050019851 Meter --> No Conversion Required

FINAL ANSWER

2.34000050019851 ≈ 2.340001 Meter <-- Radius of Curve
