Diameter of Bolt Solution

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

FIRST Step Consider the formula

d b = 0.5 \cdot \frac{d}{\sqrt{n}}

Next Step Substitute values of Variables

∴

d b = 0.5 \cdot \frac{1200mm}{\sqrt{3}}

Next Step Prepare to Evaluate

∴

d b = 0.5 \cdot \frac{1200}{\sqrt{3}}

Next Step Evaluate

∴

d b = 0.346410161513776m

Next Step Convert to Output's Unit

∴

d b = 346.410161513776mm

LAST Step Rounding Answer

∴

d b = 346.4102mm
