Mean Radius of Splines Solution

Follow our step by step solution on how to calculate Mean Radius of Splines?

FIRST Step Consider the formula

R m = \frac{D + d}{4}

Next Step Substitute values of Variables

∴

R m = \frac{60mm + 52mm}{4}

Next Step Convert Units

∴

R m = \frac{0.06m + 0.052m}{4}

Next Step Prepare to Evaluate

∴

R m = \frac{0.06 + 0.052}{4}

Next Step Evaluate

∴

R m = 0.028m

LAST Step Convert to Output's Unit

∴

R m = 28mm
