Question
A piece of copper having a rectangular cross-section of $15.2 \mathrm{~mm} \times 19.1 \mathrm{~mm}$ is pulled in tension with $44,500 \mathrm{~N}$ force, producing only elastic deformation. Calculate the resulting strain?
Step 1
This gives us $l = 15.2 \, \text{mm} = 0.152 \, \text{m}$ and $w = 19.1 \, \text{mm} = 0.191 \, \text{m}$. Show more…
