Required information

The stress$-$strain data from a tensile test on a cast$-$iron specimen are

$\backslash$table$[[({10}^{-3}),],[0,0],[0\mathrm{.}20,5],[0\mathrm{.}44,10],[0\mathrm{.}80,16],[1\mathrm{.}0,19],[1\mathrm{.}5,26],[2\mathrm{.}0,32],[2\mathrm{.}8,40],[3\mathrm{.}4,46],[4\mathrm{.}0,49],[5\mathrm{.}0,54]]$

What is the value of the $0\mathrm{.}1\%$ offset yield strength?

The yield strength is $14000k.$
