Steer Angle given Understeer Gradient Solution

Follow our step by step solution on how to calculate Steer Angle given Understeer Gradient?

FIRST Step Consider the formula

δ = (57.3 \cdot (\frac{L}{R})) + (K \cdot A α)

Next Step Substitute values of Variables

∴

δ = (57.3 \cdot (\frac{2700mm}{10000mm})) + (0.218rad \cdot 1.6m/s²)

Next Step Convert Units

∴

δ = (57.3 \cdot (\frac{2.7m}{10m})) + (0.218rad \cdot 1.6m/s²)

Next Step Prepare to Evaluate

∴

δ = (57.3 \cdot (\frac{2.7}{10})) + (0.218 \cdot 1.6)

LAST Step Evaluate

∴

δ = 15.8198rad
