Rear Track Width given Roll Rate Solution

Follow our step by step solution on how to calculate Rear Track Width given Roll Rate?

FIRST Step Consider the formula

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

Next Step Substitute values of Variables

∴

t R = \sqrt{\frac{10297.43Nm/rad \cdot 30366.46N/m \cdot {0.9m}^{2}}{(30366.46N/m \cdot \frac{{0.9m}^{2}}{2} - 10297.43Nm/rad) \cdot 321300N/m}}

Next Step Prepare to Evaluate

∴

t R = \sqrt{\frac{10297.43 \cdot 30366.46 \cdot {0.9}^{2}}{(30366.46 \cdot \frac{{0.9}^{2}}{2} - 10297.43) \cdot 321300}}

Next Step Evaluate

∴

t R = 0.627663098690719m

LAST Step Rounding Answer

∴

t R = 0.6277m
