please solution for group$2.$ Group $2$: Length $($L$)$: $368$ mm$,$ Weight $($W$)$: $1000$ g$.2.$ Determine cross$-$sectional area.

$3.$ Determine stress corresponding to each force.

$4.$ Determine longitudinal strain using gage length, $=220$ mm $($not length

$(405,368,392$ or $383)$ corresponding to each longitudinal deformation.

$5.$ Using the data given in excel spreadsheet, plot engineering stress$-$strain

diagram.

$4.$ Determine approximate yield strength, $($MPa$)$ and yield strain, $($mm$/$mm$)$

from the stress$-$strain diagram.

Remember, at yield point, the specimen deformation increases at constant stress.

$5.$ Determine the ultimate strength, $($MPa$)$ from the stress$-$strain diagram.

Remember, ultimate strength is the maximum engineering stress observed during

the testing of the specimen.

$6.$ Determine and fracture strain, $($mm$/$mm$)$ from the stress$-$strain diagram

$7.$ Calculate the modulus of toughness $($T$)$ and the modulus of resilience $($R$)$

according to the following formulas.
