Diameter of Hole Inside Bolt Solution

Follow our step by step solution on how to calculate Diameter of Hole Inside Bolt?

FIRST Step Consider the formula

d 1 = \sqrt{d^{2} - {d c}^{2}}

Next Step Substitute values of Variables

∴

d 1 = \sqrt{{15mm}^{2} - {12mm}^{2}}

Next Step Convert Units

∴

d 1 = \sqrt{{0.015m}^{2} - {0.012m}^{2}}

Next Step Prepare to Evaluate

∴

d 1 = \sqrt{{0.015}^{2} - {0.012}^{2}}

Next Step Evaluate

∴

d 1 = 0.009m

LAST Step Convert to Output's Unit

∴

d 1 = 9mm
