Problem # 1: The two rods as shown in the figure are attached to each other and the aluminum rod is fixed at the wall. The rods are initially unstressed and then a 20, 000 lb horizontal force is applied to the end of the brass rod as shown. Additionally, the rods experience a temperature increase of 80 °F. Use Linear coefficient of Expansion: 13 x 10-6/°F Brass = 11 x 10-6/°F Aluminum Young's Modulus: EAluminum = 10 x 106 lb/in²; EBrass = 15 x 106 lb/in² Determine; a) the final stress that develops in the aluminum rod, b) the total displacement of point C. Aluminum 10 ft B Aal= 2in² Brass 6 ft A₁= 1in² Abr F = 20,000 lb
