A tensile member of 2024-0 aluminum alloy used for aircraft fuselage had an original cross-sectional area of 4.0square inches. If the strain hardening exponent, n=0.21 and the strength coefficient Q=56,000 psi, determine:
a) The maximum load that can be carried by the member?
b) The change in length of the member assuming an original length of 4.0 feet?
