Task $7$:

The solid circular rod that is $600$ mm long and $20$ mm in diameter is subjected to an axial force of $P=50kN.$ The elongation of the rod is $=1\mathrm{.}10mm,$ and its diameter becomes $d^{\text{'}}=19\mathrm{.}9937mm.$ Determine the modulus of elasticity of the material. Assume that the material does not yield Express your answer to three significant figures and include the appropriate units.
