Coefficient of Adhesion Solution

Follow our step by step solution on how to calculate Coefficient of Adhesion?

FIRST Step Consider the formula

μ = \frac{F t}{W}

Next Step Substitute values of Variables

∴

μ = \frac{545N}{30000AT (US)}

Next Step Convert Units

∴

μ = \frac{545N}{875.0001kg}

Next Step Prepare to Evaluate

∴

μ = \frac{545}{875.0001}

Next Step Evaluate

∴

μ = 0.622857071667166

LAST Step Rounding Answer

∴

μ = 0.6229
