Chemistry

Explanation:

The given data is as follows.

Cross-section area of the rectangular is as follows.

Area = $10 mm \times 12.7 mm$

= $127 \times 10^{-6} m^{2}$

= $1.27 \times 10^{-4} m^{2}$

Tension applied on the specimen is 35,500 N

Now, formula to calculate the modulus of elasticity for a material of aluminium is as follows.

E = 70 GPa

= $70 \times 10^{9} Pa$

or, = $70 \times 10^{9} N/m^{2}$

Now, stress on the specimen is as follows.

$\sigma = \frac{P}{A}$

= $\frac{35000}{1.27 \times 10^{-4}}$

= $275.59 \times 10^{6} N/m^{2}$

According to Hook's law, we will calculate the resulting stain as follows.

$\sigma = E \epsilon$

$\epsilon = \frac{\sigma}{E}$

= $\frac{275.59 \times 10^{6}}{70 \times 10^{9}}$

= $3.937 \times 10^{-3} mm/mm$

Thus, we can conclude that the resulting strain is $3.937 \times 10^{-3} mm/mm$ .
