(b) Figure Q1(b) shows three rods that were assembled together and held between rigid supports. The material properties of each material are given in Table Q1(b). Suppose the initial temperature is T1 2x °C. The temperature then raised up and reaches T2 = 7y °C. Parameter x and y are given by: x = last digit of your matrix number y fifth digit of your matrix number For example, a student with the matrix number CD200187 will have the values of 2x = 27 and 7y = 78. i. Calculate the average normal stress in each material when the temperature reaches T2. ii. Determine the corresponding displacement at point A.
