Limiting force on bolt given stiffness and initial preload Solution

Follow our step by step solution on how to calculate Limiting force on bolt given stiffness and initial preload?

FIRST Step Consider the formula

F l = P i \cdot (\frac{k b' + k c'}{k c'})

Next Step Substitute values of Variables

∴

F l = 850N \cdot (\frac{75000N/mm + 1200N/mm}{1200N/mm})

Next Step Convert Units

∴

F l = 850N \cdot (\frac{7.5E+7N/m + 1.2E+6N/m}{1.2E+6N/m})

Next Step Prepare to Evaluate

∴

F l = 850 \cdot (\frac{7.5E+7 + 1.2E+6}{1.2E+6})

LAST Step Evaluate

∴

F l = 53975N
