Isosceles Triangle Method Solution

STEP 0: Pre-Calculation Summary
Formula Used
Number of Crossing = (1/2)*cosec(Angle of Crossing/2)
N = (1/2)*cosec(αCrossing/2)
This formula uses 2 Functions, 2 Variables
Functions Used
sec - Secant is a trigonometric function that is defined ratio of the hypotenuse to the shorter side adjacent to an acute angle (in a right-angled triangle); the reciprocal of a cosine., sec(Angle)
cosec - The cosecant function is a trigonometric function that is the reciprocal of the sine function., cosec(Angle)
Variables Used
Number of Crossing - Number of Crossing - Crossing or ‘frog’ is a device that provides two flangeways through which the wheels of the flanges may move when two rails intersect each other at an angle.
Angle of Crossing - (Measured in Radian) - Angle of Crossing is the angle that the gauge faces make with each other.
STEP 1: Convert Input(s) to Base Unit
Angle of Crossing: 4 Degree --> 0.0698131700797601 Radian (Check conversion ​here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
N = (1/2)*cosec(αCrossing/2) --> (1/2)*cosec(0.0698131700797601/2)
Evaluating ... ...
N = 14.3268541739246
STEP 3: Convert Result to Output's Unit
14.3268541739246 --> No Conversion Required
FINAL ANSWER
14.3268541739246 14.32685 <-- Number of Crossing
(Calculation completed in 00.005 seconds)

Isosceles triangle method

This method is important for layout of tramways
Since the angle of crossing is very small, so the difference in the values of ‘N* by different methods is also small.
