Spring Index given Wire Diameter of Inner and Outer Springs Solution

Follow our step by step solution on how to calculate Spring Index given Wire Diameter of Inner and Outer Springs?

FIRST Step Consider the formula

C = \frac{2 \cdot d 1}{d 1 - d 2}

Next Step Substitute values of Variables

∴

C = \frac{2 \cdot 6.5mm}{6.5mm - 5.5mm}

Next Step Convert Units

∴

C = \frac{2 \cdot 0.0065m}{0.0065m - 0.0055m}

Next Step Prepare to Evaluate

∴

C = \frac{2 \cdot 0.0065}{0.0065 - 0.0055}

LAST Step Evaluate

∴

C = 13
