Track Modulus given Speed Factor Solution

Follow our step by step solution on how to calculate Track Modulus given Speed Factor?

FIRST Step Consider the formula

k = {(\frac{V t}{18.2 \cdot F sf})}^{2}

Next Step Substitute values of Variables

∴

k = {(\frac{149km/h}{18.2 \cdot 2})}^{2}

Next Step Prepare to Evaluate

∴

k = {(\frac{149}{18.2 \cdot 2})}^{2}

Next Step Evaluate

∴

k = 164.320007132279Pa

Next Step Convert to Output's Unit

∴

k = 16.7559775389446kgf/m²

LAST Step Rounding Answer

∴

k = 16.756kgf/m²

Go Speed Factor

F sf = \frac{V t}{18.2 \cdot \sqrt{k}}

Go Speed given Speed Factor

V t = F sf \cdot (18.2 \cdot \sqrt{k})

Go Speed Factor according to German Formula

F sf = \frac{{V t}^{2}}{30000}

Go Speed using German Formula

V t = \sqrt{F sf \cdot 30000}
