Question $1$

Below is a table with laboratory results for a specimen with $12\mathrm{.}8[mm]$ of original diameter Construct the stress strain curve using MSEXCEL. Then identify the elastic deformation regon

and estimate the modulus of elasticity of the specimen under lest $($you can use the linear regression function$)$ Finally indicate the nght answer

Calculate the tensile strength of the speamen Then seled the night answer

$6\mathrm{.}3{10}^2[N]$

$4\mathrm{.}9{10}^3[MPa]$

$5\mathrm{.}7{10}^3[MPa]$
