Spring Minimum Tensile Strength Calculator
minimum tensile strength (TS) calculator - step by step calculation, formula & solved example problem to find the capacity of spring material to withstand loads tending to elongate. Spring material constant A, diameter d & exponent m are the key terms of this calculation.
Formula for Spring Tensile Strength
In mechanical engineering, the below mathematical formula is used to calculate the minimum tensile strength Sut of a spring material.
| Material | ASTM | A in kpsi | A in Mpa | m |
|---|---|---|---|---|
| music wire | A228 | 186 | 2060 | 0.163 |
| oil-temtered wire | A229 | 146 | 1610 | 0.193 |
| hard-drawn wire | A227 | 137 | 1510 | 0.201 |
| chrome vanadium | A232 | 173 | 1790 | 0.155 |
| chrome silicon | A401 | 218 | 1960 | 0.091 |
Solved Example
The below step by step solved example problem may helpful for users to understand how the input values are being used in such calculations to find the capacity of material to withstand loads tending to elongate.
Example Problem
Find the minimum tensile strength of spring material (ASTM A227) having diameter d = 7 mm, constant A = 137 kpsi & exponent m = 0.201.
Solution
The given data
constant A = 1510 kpsi
diameter d = 7 mm
exponent m = 0.201
Step by step calculation
Formula to find Sut = A/dm
substitute the values in the above formula
= 137/70.201
Sut = 92.65 kpsi
