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
