Rate of Increase of Radial Acceleration Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables Used

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.
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.
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.

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
Radius of Curve: 300 Meter --> 300 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

a_c = (3.15*(V_v)^3)/(L*R_t) --> (3.15*(41)^3)/(361.83*300)

Evaluating ... ...

a_c = 2.00002901915264

STEP 3: Convert Result to Output's Unit

2.00002901915264 --> No Conversion Required

FINAL ANSWER

2.00002901915264 ≈ 2.000029 <-- Rate of Increase of Radial Acceleration
