Buckling Stiffness Factor Solution

Follow our step by step solution on how to calculate Buckling Stiffness Factor?

FIRST Step Consider the formula

C T = 1 + (\frac{K M \cdot L e}{K T \cdot E})

Next Step Substitute values of Variables

∴

C T = 1 + (\frac{1200 \cdot 2380mm}{0.59 \cdot 50MPa})

Next Step Convert Units

∴

C T = 1 + (\frac{1200 \cdot 2.38m}{0.59 \cdot 50MPa})

Next Step Prepare to Evaluate

∴

C T = 1 + (\frac{1200 \cdot 2.38}{0.59 \cdot 50})

Next Step Evaluate

∴

C T = 97.8135593220339

LAST Step Rounding Answer

∴

C T = 97.8136
