Force on Key Solution

Follow our step by step solution on how to calculate Force on Key?

FIRST Step Consider the formula

F = 2 \cdot \frac{M t}{d s}

Next Step Substitute values of Variables

∴

F = 2 \cdot \frac{224500N*mm}{45mm}

Next Step Convert Units

∴

F = 2 \cdot \frac{224.5N*m}{0.045m}

Next Step Prepare to Evaluate

∴

F = 2 \cdot \frac{224.5}{0.045}

Next Step Evaluate

∴

F = 9977.77777777778N

LAST Step Rounding Answer

∴

F = 9977.7778N
