A cylindrical rod 100 mm long and having a diameter of 10.0 mm is to be deformed using a tensile load of 27,500 N. It must not experience either plastic deformation or a diameter reduction of more than 7.5 × 10−3 mm. Of the materials listed as follows, which are possible candidates? Justify your choice(s).
Material | Modulus of Elasticity | Yield Strength (GPa) | Poisson’s (MPa) | Ratio |
Aluminum alloy | 70 | 200 | 0.33 |
|
Brass alloy | 101 | 300 | 0.34 |
|
Steel alloy | 207 | 400 | 0.30 |
|
Titanium alloy | 107 | 650 | 0.34 |
