Speed given Speed Factor Solution

STEP 0: Pre-Calculation Summary

Formula Used

Speed of Train = Speed Factor*(18.2*sqrt(Track Modulus))
V_t = F_sf*(18.2*sqrt(k))
This formula uses 1 Functions, 3 Variables

Functions Used

sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)

Variables Used

Speed of Train - (Measured in Kilometer per Hour) - Speed of Train is the rate at which the object covers a specific distance.
Speed Factor - Speed Factor is a value which is used to change the static rail load to a dynamic rail load.
Track Modulus - (Measured in Kilogram-Force per Square Meter) - Track modulus is the vertical stiffness of rail foundation.

STEP 1: Convert Input(s) to Base Unit

Speed Factor: 2 --> No Conversion Required
Track Modulus: 15 Kilogram-Force per Square Meter --> 15 Kilogram-Force per Square Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

V_t = F_sf*(18.2*sqrt(k)) --> 2*(18.2*sqrt(15))

Evaluating ... ...

V_t = 140.97659380195

STEP 3: Convert Result to Output's Unit

39.1601649449861 Meter per Second -->140.97659380195 Kilometer per Hour (Check conversion here)

FINAL ANSWER

140.97659380195 ≈ 140.9766 Kilometer per Hour <-- Speed of Train

(Calculation completed in 00.004 seconds)
