Nominal Diameter of Bolt given Wrench Torque Solution

Follow our step by step solution on how to calculate Nominal Diameter of Bolt given Wrench Torque?

FIRST Step Consider the formula

d = \frac{M t}{0.2 \cdot P i}

Next Step Substitute values of Variables

∴

d = \frac{49500N*mm}{0.2 \cdot 16500N}

Next Step Convert Units

∴

d = \frac{49.5N*m}{0.2 \cdot 16500N}

Next Step Prepare to Evaluate

∴

d = \frac{49.5}{0.2 \cdot 16500}

Next Step Evaluate

∴

d = 0.015m

LAST Step Convert to Output's Unit

∴

d = 15mm
