Question
The rigid bar ABC as shown in the figure is
pinned supported at B and attached to the
vertical two rods. Initially, the bar is
horizontal and the vertical rods are stress-
free. The temperature in the steel rod is
decreased by 42°C. Neglect the weight of the
bar
Steel
L = 900 mm
A = 300 mm²
E = 200 GPa
a = 11.7 x 10-6/°C
AT = -42°C
1m
3 m
Aluminum
L = 1320 mm
A = 1200 mm²
E = 70 GPa
a = 23 x 10-6/⁰C
Determine the deformation at steel if we will
consider only the effect of change in
temperature.
