L = (3.15*(Vv^3))/(Rt*ac)
This formula uses 4 Variables
Variables Used
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.
Vehicle Velocity - (Measured in Kilometer per Hour) - The Vehicle Velocity is referred as amount of distance vehicle travelled in a particular time.
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.
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
Radius of Curve: 300 Meter --> 300 Meter No Conversion Required
Rate of Increase of Radial Acceleration: 2 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
L = (3.15*(Vv^3))/(Rt*ac) --> (3.15*(41^3))/(300*2)
Evaluating ... ...
L = 361.83525
STEP 3: Convert Result to Output's Unit
361.83525 Meter --> No Conversion Required
FINAL ANSWER
361.83525 361.8352 Meter <-- Minimum Length of Spiral
