Rate of Super Elevation Solution

STEP 0: Pre-Calculation Summary

Formula Used

Rate of Super Elevation = (0.75*Velocity^2)/([g]*Mean Radius of Curve)
e = (0.75*v_vehicle^2)/([g]*R_mean)
This formula uses 1 Constants, 3 Variables

Constants Used

[g] - Gravitational acceleration on Earth Value Taken As 9.80665

Variables Used

Rate of Super Elevation - Rate of Super Elevation is the rate at which the outer rail is raised above the inner rail in a curve to balance centrifugal force.
Velocity - (Measured in Meter per Second) - Velocity is the rate of change of an object's position with respect to time, used in superelevation design to ensure safe and efficient traffic flow.
Mean Radius of Curve - (Measured in Meter) - Mean Radius of Curve is the average radius of a curve section in road design, used to calculate superelevation and widening of the road.

STEP 1: Convert Input(s) to Base Unit

Velocity: 28.23 Meter per Second --> 28.23 Meter per Second No Conversion Required
Mean Radius of Curve: 340 Meter --> 340 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

e = (0.75*v_vehicle^2)/([g]*R_mean) --> (0.75*28.23^2)/([g]*340)

Evaluating ... ...

e = 0.179260014437982

STEP 3: Convert Result to Output's Unit

0.179260014437982 --> No Conversion Required

FINAL ANSWER

0.179260014437982 ≈ 0.17926 <-- Rate of Super Elevation
