Stress Concentration Factor at Outer Fibers of Coils Solution

STEP 0: Pre-Calculation Summary

Formula Used

Stress Concentration Factor at Outer Fibres = (4*Spring Index of Coil Spring^2+Spring Index of Coil Spring-1)/(4*Spring Index of Coil Spring*(Spring Index of Coil Spring+1))
K_o = (4*C^2+C-1)/(4*C*(C+1))
This formula uses 2 Variables

Variables Used

Stress Concentration Factor at Outer Fibres - Stress Concentration Factor at Outer Fibres is simply a measure of the degree to which external stress is amplified at the tip of a crack.
Spring Index of Coil Spring - Spring index of coil spring is defined as the ratio of mean coil diameter of the spring to the diameter of the spring Wire.

STEP 1: Convert Input(s) to Base Unit

Spring Index of Coil Spring: 5 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

K_o = (4*C^2+C-1)/(4*C*(C+1)) --> (4*5^2+5-1)/(4*5*(5+1))

Evaluating ... ...

K_o = 0.866666666666667

STEP 3: Convert Result to Output's Unit

0.866666666666667 --> No Conversion Required

FINAL ANSWER

0.866666666666667 ≈ 0.866667 <-- Stress Concentration Factor at Outer Fibres
