A composite circular bar consisting of two sections is shown in Figure Q.4(a). If the Young's Modulus of Section 1 and Section 2 are 200 x 10' N/m and 70 x 10 N/m respectively, calculate : (i) the stress and strain in Section 1 of the bar; (ii) the stress and strain in Section 2 of the bar; and (4 marks) (4 marks) (iii) the total reduction in length of the bar due to the compressive force of 240 kN.
