A 1-cm diameter steel cable with a yield strength of 480 MPa needs to be replaced to reduce the overall weight of the cable. Which of the following aluminum alloys could be a potential replacement?
(a) 3004-H18 (Sy = 248 MPa);
(b) 1100-H18 (Sy = 151 MPa);
(c) 4043-H18 (Sy = 269 MPa); and
(d) 5182-O (Sy = 131 MPa).
The density of the steel used in the cable was 7.87 g/cm3, and assume that the density of all the aluminum alloys listed above is 2.7 g/cm3.
