Here is how the Friction Coefficient between Wheels and Road Surface at Rear Wheel equation looks like.

0.58 = \frac{2.4 - \frac{1.3}{1 - \frac{6710.334}{15000 \cdot \cos (12)}}}{0.0075}

0.58 = \frac{2.4m - \frac{1.3m}{1 - \frac{6710.334N}{15000N \cdot \cos (12°)}}}{0.0075m}

0.58 = \frac{2.4 - \frac{1.3}{1 - \frac{6710.334}{15000 \cdot \cos (12)}}}{0.0075}

Friction Coefficient between Wheels and Road Surface at Rear Wheel Solution

Follow our step by step solution on how to calculate Friction Coefficient between Wheels and Road Surface at Rear Wheel?

FIRST Step Consider the formula

μ = \frac{b - \frac{x}{1 - \frac{R r}{W \cdot \cos (θ)}}}{h}

Next Step Substitute values of Variables

∴

μ = \frac{2.4m - \frac{1.3m}{1 - \frac{6710.334N}{15000N \cdot \cos (12°)}}}{0.0075m}

Next Step Convert Units

∴

μ = \frac{2.4m - \frac{1.3m}{1 - \frac{6710.334N}{15000N \cdot \cos (0.2094rad)}}}{0.0075m}

Next Step Prepare to Evaluate

∴

μ = \frac{2.4 - \frac{1.3}{1 - \frac{6710.334}{15000 \cdot \cos (0.2094)}}}{0.0075}

Next Step Evaluate

∴

μ = 0.579993871799959

LAST Step Rounding Answer

∴

μ = 0.58
