σ (MPa) 490 0.007 e (mm/mm) A specimen has the stress-strain diagram shown. The specimen has an original diameter of 12.4 mm, and its modulus of rigidity is 27.4 GPa. Determine the specimen's diameter when the longitudinal stress is 325 MPa.

1) An airplane's weight change is determined by reading the strain gauge A mounted on the plane's aluminum wheel strut. Before the plane is loaded, the strain gauge reading in the strut is &₁ = 0.00100 in./in., whereas after loading &2 = 0.00243 in./in. Determine the change in the force on the strut if the cross-sectional area of the strut is 3.5 in². and E = 10(10³) Ksi. O

The elastic portion of the stress-strain diagram for an aluminum alloy is shown in the figure below (Figure 1).
