A rigid bar is supported by two copper ro
ds and the gap (A) between the aluminu
m rod and the bar is 1.50 mm. If the temp
erature for all materials is increased by 4
0 degrees Celsius, what is the thermal str
ess of the aluminum rod? Disregard the
weight of the rigid bar.
For each copper bar,
A = 500 mm^2, E = 120 GPa, and a = 1
6.8 μm/(m. C).
For the aluminum bar,
A = 400 mm^2, E = 70 GPa, and a = 23.

the cross-sectional area of the bar 1 of the two bars supported on the left and right sides is 1.2 cm^2, the coefficient of thermal expansion is 20.9 10^(-6)/K; The cross-sectional area of bar 2 is 3 cm^2 and its coefficient of thermal expansion is 25.4 10^(-6)/K. Since the modulus of elasticity of the material is 207 GPa, these two bars are heated to 99 °C.a) What will be the change in length (mm) of bar 1?b) What is the stress in bar 1 in MPa?c) What is the stress in bar 2 in MPa?
6 A steel pipe with a 50 mm outside diameter and a 43.75
'mm inside diameter surrounds a solid brass rod 37.5 mm
in diameter as shown. Both materials are joined to a
rigid cover plate at each end. The assembly is free to
expand longitudinally. The assembly is stress free at a
temperature of 27°C. For steel, Young's modulus is 200
GN/m², and the coefficient of linear thermal expansion
is 11.7x10-6 1/°C. For brass, Young's modulus is 93.33
GN/m², and the coefficient of linear thermal expansion
is 1.872 x 10-5 1/°C. What is the stress in the steel
tube when the temperature is raised to 121°C?
