Tyre Rate given Roll Rate Solution

Follow our step by step solution on how to calculate Tyre Rate given Roll Rate?

FIRST Step Consider the formula

K t = \frac{K Φ \cdot (K w \cdot \frac{{T s}^{2}}{2})}{(K w \cdot \frac{{T s}^{2}}{2} - K Φ) \cdot \frac{{t R}^{2}}{2}}

Next Step Substitute values of Variables

∴

K t = \frac{10297.43Nm/rad \cdot (30366.46N/m \cdot \frac{{0.9m}^{2}}{2})}{(30366.46N/m \cdot \frac{{0.9m}^{2}}{2} - 10297.43Nm/rad) \cdot \frac{{0.4m}^{2}}{2}}

Next Step Prepare to Evaluate

∴

K t = \frac{10297.43 \cdot (30366.46 \cdot \frac{{0.9}^{2}}{2})}{(30366.46 \cdot \frac{{0.9}^{2}}{2} - 10297.43) \cdot \frac{{0.4}^{2}}{2}}

Next Step Evaluate

∴

K t = 791122.863760417N/m

LAST Step Rounding Answer

∴

K t = 791122.8638N/m
