A particular rod for the structure of a spacecraft must be able to withstand an applied force, but still function properly. Compare the properties of aluminum 7075-T6 and AISI 1015 steel to decide which is best for the problem described below. The dimensions of the rod are as follows: volume of 10 m', cross-sectional area of 0.1 m2, factor of safety of 2, and a ơmax of 150 MPa. The physical properties of the aluminum 7075-T6 are: Oyield of 505 MPa and density, p, equal to 2810 kg/m'; and the properties of AISI 1015 steel are oyield of 315 MPa and density, p, equal to 7870 kg/m A particular rod for the structure of a spacecraft must be able to withstand an applied force, but still function properly.
