Wire Diameter of Inner Spring given Wire Diameter of Outer Spring and Spring Index Solution

STEP 0: Pre-Calculation Summary

Formula Used

Wire Diameter of Inner Spring = (Spring Index of Coil Spring/(Spring Index of Coil Spring-2))*Wire Diameter of Outer Spring
d₂ = (C/(C-2))*d₁
This formula uses 3 Variables

Variables Used

Wire Diameter of Inner Spring - (Measured in Meter) - The Wire Diameter of Inner Spring is defined as the diameter or the thickness of the inner spring wire.
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.
Wire Diameter of Outer Spring - (Measured in Meter) - Wire Diameter of Outer Spring is defined as the diameter or the thickness of the outer spring wire.

STEP 1: Convert Input(s) to Base Unit

Spring Index of Coil Spring: 5 --> No Conversion Required
Wire Diameter of Outer Spring: 6.5 Millimeter --> 0.0065 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

d₂ = (C/(C-2))*d₁ --> (5/(5-2))*0.0065

Evaluating ... ...

d₂ = 0.0108333333333333

STEP 3: Convert Result to Output's Unit

0.0108333333333333 Meter -->10.8333333333333 Millimeter (Check conversion here)

FINAL ANSWER

10.8333333333333 ≈ 10.83333 Millimeter <-- Wire Diameter of Inner Spring

(Calculation completed in 00.020 seconds)

What are concentric springs?

A concentric spring consists of two helical compression springs, one inside the other, having the same axis.
Concentric spring is also called a ‘nested’ spring. In general, there are two springs one inside other.
