A cylindrical rod 120 mm long and having a diameter of 15.0 mm is to be deformed using a tensile load of 35,000 N. It must not experience either plastic deformation or a diameter reduction of more than 1.2 × 10–2 mm. Of the following materials listed, which are possible candidates? Justify your choice(s).
Material | Modulus of Elasticity (GPa) | Yield Strength (MPa) | Poisson’s Ratio |
Aluminum alloy | 70 | 250 | 0.33 |
Titanium alloy | 105 | 850 | 0.36 |
Steel alloy | 205 | 550 | 0.27 |
Magnesium alloy | 45 | 170 | 0.35 |
