Radius of Curve given Extra Width Solution

STEP 0: Pre-Calculation Summary
Formula Used
Radius of Curve = (Wheelbase+Lap of Flange^2)*125/Extra Width
R = (W+L^2)*125/We
This formula uses 4 Variables
Variables Used
Radius of Curve - (Measured in Millimeter) - Radius of Curve is the radius of a circle whose part, say, arc is taken for consideration.
Wheelbase - (Measured in Millimeter) - Wheelbase is the horizontal distance between the centers of the front and rear wheels.
Lap of Flange - (Measured in Millimeter) - Lap of flange refers to the projecting edge or rim on the circumference of a steel wheel that is designed to keep the wheel on a rail.
Extra Width - (Measured in Millimeter) - Extra width refers to the widened width of the track at curves.
STEP 1: Convert Input(s) to Base Unit
Wheelbase: 3500 Millimeter --> 3500 Millimeter No Conversion Required
Lap of Flange: 50 Millimeter --> 50 Millimeter No Conversion Required
Extra Width: 2.18 Millimeter --> 2.18 Millimeter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
R = (W+L^2)*125/We --> (3500+50^2)*125/2.18
Evaluating ... ...
R = 344036.697247706
STEP 3: Convert Result to Output's Unit
344.036697247706 Meter --> No Conversion Required
FINAL ANSWER
344.036697247706 344.0367 Meter <-- Radius of Curve

6 Lap of Flange Calculators

Lap of Flange given Extra Width of Track
Go Lap of Flange = sqrt((Extra Width*Radius of Curve/125)-Wheelbase)
Lap of Flange given Diameter of Wheel
Go Lap of Flange = 2*((Diameter of Wheel*Depth of Wheel Flange)+Depth of Wheel Flange^2)^0.5
Diameter of Wheel given Lap of Flange
Go Diameter of Wheel = ((Lap of Flange/2)^2-Depth of Wheel Flange^2)/Depth of Wheel Flange
Radius of Curve given Extra Width
Go Radius of Curve = (Wheelbase+Lap of Flange^2)*125/Extra Width
Wheel Base given Extra Width
Go Wheelbase = (Extra Width*Radius of Curve/125)-Lap of Flange^2
Extra Track Width in Curves
Go Extra Width = (Wheelbase+Lap of Flange^2)*125/Radius of Curve

Radius of Curve given Extra Width Formula

Radius of Curve = (Wheelbase+Lap of Flange^2)*125/Extra Width
R = (W+L^2)*125/We

Why Extra Widening is provided at curves?

This Extra Width is the result of extra widening of the pavement at the curves. There is a tendency of the driver to take the outer path at the curves to have more sight distance visible ahead. While overtaking operations on horizontal curves driver will need more spacing from the other vehicles to feel safer.
