A plastic bar ACB having two different solid circular sections is held between rigid supports as shown in the figure. The diameters in the left- and right-hand parts are 50 mm and 75 mm, respectively. The corresponding lengths are 230 mm and 320 mm. The modulus of elasticity E is 6 GPa & the coefficient of thermal expansion α is 10-4 /0C. The bar is subjected to uniform temperature increase of 300C. Determine: i. maximum compressive stress in the bar. ii. displacement of point C.
