Analysis of stress$-$strain data

Tensile testing allows engineers to determine fundamental properties of a material. In this problem, you will compute some of these properties using actual data

collected from an unspecified steel specimen. The data are provided in the file TensileTestDataSI.xlsx$,$ which has already been added to the same folder as your

script. The first column contains displacement, in $mm.$ The second column contains the corresponding tensile force, in $N.$ A plot of the raw data and preview of the

first few rows of the table are shown below.

Specimen parameters were:

$L_0=63\mathrm{.}5mm$

$w=2\mathrm{.}54mm$

$h=12\mathrm{.}7mm$

Your script should load the data into MATLAB and complete the following tasks:

Calculate the cross sectional area of the specimen in meters ${?}^2.$ Assign the value to a variable named area.

Compute the Modulus of Elasticity in Pascal. Assign the value to a variable named $E.$

Determine the Yield Strength $($in Pascal$)$ of the sample using an offset of $0\mathrm{.}2\%.$ Assign the value to a variable named yield.

Find the Ultimate Tensile Strength in Pascal. Assign the value to a variable named ultimate.

Find the Fracture Strength in Pascal. Assign the value to a variable named fracture.

You may neglect the effect of strain rate, and can assume a constant cross$-$sectional area.
