Elongation of Bolt under Action of Pre Load Solution

Follow our step by step solution on how to calculate Elongation of Bolt under Action of Pre Load?

FIRST Step Consider the formula

ẟ b = \frac{P i}{k b'}

Next Step Substitute values of Variables

∴

ẟ b = \frac{16500N}{317000N/mm}

Next Step Convert Units

∴

ẟ b = \frac{16500N}{3.2E+8N/m}

Next Step Prepare to Evaluate

∴

ẟ b = \frac{16500}{3.2E+8}

Next Step Evaluate

∴

ẟ b = 5.20504731861199E-05m

Next Step Convert to Output's Unit

∴

ẟ b = 0.0520504731861199mm

LAST Step Rounding Answer

∴

ẟ b = 0.0521mm
