The formula to calculate the Critical Curve Speed (V) is:
\[ V = \sqrt{\frac{15 \cdot f \cdot R}{1 + (f \cdot e)}} \]
Where:
Critical curve speed is the maximum speed at which a vehicle can safely navigate a curve without losing traction. This speed is influenced by factors such as the friction between the tires and the road, the radius of the curve, and the superelevation (banking) of the road. Understanding and calculating the critical curve speed is essential for designing safe roadways and for drivers to maintain control of their vehicles while navigating curves.
Let's assume the following values:
Using the formula to calculate the Critical Curve Speed (V):
\[ V = \sqrt{\frac{15 \cdot 0.3 \cdot 50}{1 + (0.3 \cdot 0.05)}} \approx 18.89 \]
The Critical Curve Speed (V) is approximately 18.89 m/s.
