**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.

In mechanical engineering, the below mathematical formula is used to calculate the minimum tensile strength S_{ut} 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 |

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 S_{ut} = A/d^{m}

substitute the values in the above formula

= 137/7^{0.201}

**S _{ut} = 92.65 kpsi**
