Question

PLEASE ANSWER ASAP TY!

The two bars (1) and (2) are made of the aluminum with E = 70 GPa, has the same cross section of 100 mm x 20 mm, and supported by rigid supports at A and C. The coefficient of thermal expansion of the material is 23 x 10^–6/^oC. At T = 25^oC, the two bars have a gap of 5 mm as shown.

a) What is the reaction force (in KN) at fixed support A when the temperature is 100^oC?

b) What is the reaction force (in KN) at fixed support C when the temperature is 100^oC?

c) What is the stress (in MPa) in bar (1) when the temperature is 100^oC?

d) What is the stress (in MPa) in bar (2) when the temperature is 100^oC?

The two bars (1) and (2) are made of the aluminum with E = 70 GPa, has the same cross section
