Consider the figure shown
Bronze
A = 1500 mm2
E = 105 GPa
\(\alpha = 21.6 \times {10^{ - 6}}/^\circ C\)
Aluminum
A = 1800 mm2
E = 73 GPa
\(\alpha = 23.2 \times {10^{ - 6}}/^\circ C\)
The bars are subjected to a temperature rise of 96°C.
1
The compressive force in the bars = 217.36 KN
2
The corresponding change in length of the Bronze bar = 0.2425 mm
3
The compressive force in the bars = 271.25 KN
4
The corresponding change in length of the Bronze bar = 0.1215 mm
