25. Compute the axial stress of the aluminum rod in the figure if the temperature of the steel rod is
increased by 30 degrees Celsius. Assume that the horizontal bar ABC is rigid.
A
Steel
L = 0.9 m
A = 300 mm²
E = 200 x 10° N/m²
a = 11.7 μm/(m-°C)
B
0.6 m
Aluminum
L = 1.2 m
A = 1200 mm²
E = 70 x 10° N/m²
a = 23 μm/(m-°C)
1.2 m
