Spring Index given Shear stress in Spring Solution

Follow our step by step solution on how to calculate Spring Index given Shear stress in Spring?

FIRST Step Consider the formula

C = 𝜏 \cdot \frac{π \cdot d^{2}}{K \cdot 8 \cdot P}

Next Step Substitute values of Variables

∴

C = 230N/mm² \cdot \frac{π \cdot {4mm}^{2}}{1.1619 \cdot 8 \cdot 138.2N}

Next Step Substitute values of Constants

∴

C = 230N/mm² \cdot \frac{3.1416 \cdot {4mm}^{2}}{1.1619 \cdot 8 \cdot 138.2N}

Next Step Convert Units

∴

C = 2.3E+8Pa \cdot \frac{3.1416 \cdot {0.004m}^{2}}{1.1619 \cdot 8 \cdot 138.2N}

Next Step Prepare to Evaluate

∴

C = 2.3E+8 \cdot \frac{3.1416 \cdot {0.004}^{2}}{1.1619 \cdot 8 \cdot 138.2}

Next Step Evaluate

∴

C = 8.99999974124296

LAST Step Rounding Answer

∴

C = 9
