Radius of Circular Curve Minimum Length Solution

STEP 0: Pre-Calculation Summary

Formula Used

Radius of Curve = (3.15*(Vehicle Velocity^3))/(Minimum Length of Spiral*Rate of Increase of Radial Acceleration)
R_t = (3.15*(V_v^3))/(L*a_c)
This formula uses 4 Variables

Variables Used

Radius of Curve - (Measured in Meter) - The Radius of Curve is defined as the horizontal curve with a specific radius which quantifies smoothness and ease of vehicle movement through a curve.
Vehicle Velocity - (Measured in Kilometer per Hour) - The Vehicle Velocity is referred as amount of distance vehicle travelled in a particular time.
Minimum Length of Spiral - (Measured in Meter) - The Minimum Length of Spiral is defined as a horizontal circular curve, a vehicle and its contents are immediately subjected to centrifugal forces.
Rate of Increase of Radial Acceleration - The Rate of Increase of Radial Acceleration is referred as gradual increase in acceleration experienced by an object moving in a circular path.

STEP 1: Convert Input(s) to Base Unit

Vehicle Velocity: 41 Kilometer per Hour --> 41 Kilometer per Hour No Conversion Required
Minimum Length of Spiral: 361.83 Meter --> 361.83 Meter No Conversion Required
Rate of Increase of Radial Acceleration: 2 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

R_t = (3.15*(V_v^3))/(L*a_c) --> (3.15*(41^3))/(361.83*2)

Evaluating ... ...

R_t = 300.004352872896

STEP 3: Convert Result to Output's Unit

300.004352872896 Meter --> No Conversion Required

FINAL ANSWER

300.004352872896 ≈ 300.0044 Meter <-- Radius of Curve
