Addendum of Gear given Addendum Circle Diameter Solution

Follow our step by step solution on how to calculate Addendum of Gear given Addendum Circle Diameter?

FIRST Step Consider the formula

h a = \frac{d a - d}{2}

Next Step Substitute values of Variables

∴

h a = \frac{138mm - 118mm}{2}

Next Step Convert Units

∴

h a = \frac{0.138m - 0.118m}{2}

Next Step Prepare to Evaluate

∴

h a = \frac{0.138 - 0.118}{2}

Next Step Evaluate

∴

h a = 0.01m

LAST Step Convert to Output's Unit

∴

h a = 10mm
