Question

Three bars each made of same material are connected together and placed
between two walls when temperature is T1 = 12°C.

(a) Determine the temperature in which the first element yield (Tyield)

(b) Increase further temperature from the obtained Tyield by further 50°C degrees, then determine the distance of Point B from two walls and the thermal stress generated in each bars. The material properties and cross-sectional area of each bar are given in the figure

a=25(E-6)/C
A=20mm
