Height of Centre of Gravity from Roll Axis given Rear Lateral Load Transfer Solution

Follow our step by step solution on how to calculate Height of Centre of Gravity from Roll Axis given Rear Lateral Load Transfer?

FIRST Step Consider the formula

H = \frac{W r - \frac{a}{b} \cdot Z rr}{\frac{A y}{[g]} \cdot \frac{m}{t r} \cdot \frac{K Φr}{K Φf + K Φr}}

Next Step Substitute values of Variables

∴

H = \frac{161.87kg - \frac{27m}{2.7m} \cdot 0.0762m}{\frac{9.81m/s²}{[g]} \cdot \frac{155kg}{1.4m} \cdot \frac{67800Nm/rad}{94900Nm/rad + 67800Nm/rad}}

Next Step Substitute values of Constants

∴

H = \frac{161.87kg - \frac{27m}{2.7m} \cdot 0.0762m}{\frac{9.81m/s²}{9.8066m/s²} \cdot \frac{155kg}{1.4m} \cdot \frac{67800Nm/rad}{94900Nm/rad + 67800Nm/rad}}

Next Step Prepare to Evaluate

∴

H = \frac{161.87 - \frac{27}{2.7} \cdot 0.0762}{\frac{9.81}{9.8066} \cdot \frac{155}{1.4} \cdot \frac{67800}{94900 + 67800}}

Next Step Evaluate

∴

H = 3.49078395500421m

LAST Step Rounding Answer

∴

H = 3.4908m
