Step 1
We are given a cylindrical specimen of brass with an initial length (L) of 60 mm that is allowed to elongate by 10.8 mm under a tensile load of 40 kN. We need to find the radius of the specimen and the maximum load it can take before it gets plastically deformed. Show more…

A cylindrical specimen of a brass alloy having a length of $100 \mathrm{mm}$ (4 in.) must elongate only $5 \mathrm{mm}(0.2$ in.) when a tensile load of $100,000 \mathrm{N}\left(22,500 \mathrm{lb}_{\mathrm{f}}\right)$ is applied. Under these circumstances what must be the radius of the specimen? Consider this brass alloy to have the stress-strain behavior shown in Figure 6.12.
A cylindrical specimen of a brass alloy having a length of $100 \mathrm{~mm}$ (4 in.) must elongate only $5 \mathrm{~mm}$ (0.2 in.) when a tensile load of $100,000 \mathrm{~N}(22,500$ $\left.\mathrm{lb}_{\mathrm{}}\right)$ is applied. Under these circumstances, what must be the radius of the specimen? Consider this brass alloy to have the stress-strain behavior shown in Figure 6.12.
For a brass alloy, the stress at which plastic deformation begins is $345 \mathrm{MPa}(50,000 \mathrm{psi})$ and the modulus of elasticity is 103 GPa $\left(15.0 \times 10^{6} \mathrm{psi}\right)$. (a) What is the maximum load that may be applied to a specimen with a cross-sectional area of $130 \mathrm{mm}^{2}\left(0.2 \text { in. }^{2}\right)$ without plastic deformation? (b) If the original specimen length is $76 \mathrm{mm}$ $(3.0 \text { in. }),$ what is the maximum length to which it may be stretched without causing plastic deformation?
