Expert Solution
Step 1

Given, A compound axial member made of Aluminum and copper

Diameter of the axial member, d=1.45 in.

Youngs modulus, E1=10000 ksi and E2=17000 ksi

Length of segment, L1=88in and L2=128 in.

The area of cross section of both segments are same, A1=A2=A

Area,A=π4d2=π41.452=1.6513 in2
