Allowable Centrifugal Acceleration given Length Solution

STEP 0: Pre-Calculation Summary

Formula Used

Allowable Centrifugal Acceleration = ((Upgrade)-(Downgrade))*Vehicle Velocity^2/(100*Length of Curve)
f = ((g₁)-(g₂))*V^2/(100*L_c)
This formula uses 5 Variables

Variables Used

Allowable Centrifugal Acceleration - (Measured in Meter per Square Second) - Allowable Centrifugal Acceleration is the maximum limit for the centrifugal acceleration for comfort travel through vertical curves.
Upgrade - Upgrade is the gradient or the slope which is towards the crest of a curve. Mentioned by %.
Downgrade - Downgrade is the gradient or the slope which is guided to the downward direction of a curve. Mentioned by %.
Vehicle Velocity - (Measured in Kilometer per Hour) - Vehicle Velocity can be described as the amount of distance a vehicle traveled in a particular time.
Length of Curve - (Measured in Meter) - Length of Curve is determined by the permissible rate of change of grade or from centrifugal consideration as appropriate.

STEP 1: Convert Input(s) to Base Unit

Upgrade: 2.2 --> No Conversion Required
Downgrade: -1.5 --> No Conversion Required
Vehicle Velocity: 100 Kilometer per Hour --> 100 Kilometer per Hour No Conversion Required
Length of Curve: 616 Meter --> 616 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

f = ((g₁)-(g₂))*V^2/(100*L_c) --> ((2.2)-((-1.5)))*100^2/(100*616)

Evaluating ... ...

f = 0.600649350649351

STEP 3: Convert Result to Output's Unit

0.600649350649351 Meter per Square Second --> No Conversion Required

FINAL ANSWER

0.600649350649351 ≈ 0.600649 Meter per Square Second <-- Allowable Centrifugal Acceleration
