Question

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. Wich of the following aluminum alloys could be a potential replacement?

3004-H18 (Sy=248 MPa)

1100-H18 (Sy=151 MPa)

4043-H18 (Sy=269 MPa)

5182-O (Sy=131 MPa)

Answer 1

To determine the potential replacement for the steel cable, we need to compare the yield strengths of the aluminum alloys to the yield strength of the steel cable. The aluminum alloy 4043-H18 could be a potential replacement.

Step-by-step explanation:

To determine which aluminum alloy could potentially replace the 1-cm-diameter steel cable, we need to compare the yield strengths of the aluminum alloys to the yield strength of the steel cable. The aluminum alloy with a yield strength that is higher than the yield strength of the steel cable (480 MPa) can be considered as a potential replacement.

Comparing the yield strengths:

• 3004-H18 (Sy=248 MPa) - Lower than the yield strength of the steel cable, not a potential replacement.
• 1100-H18 (Sy=151 MPa) - Lower than the yield strength of the steel cable, not a potential replacement.
• 4043-H18 (Sy=269 MPa) - Higher than the yield strength of the steel cable, potential replacement.
• 5182-O (Sy=131 MPa) - Lower than the yield strength of the steel cable, not a potential replacement.

Based on the comparison, the aluminum alloy 4043-H18 could be a potential replacement for the steel cable.
