Question 2A composite bar is made up of a steel strip 2 mm thick and 12 mm wide, sandwichedbetween two aluminium strips each 3 mm thick and 12 mm wide. The three strips areheld together by two rivets of 5 mm diameter each.2.1 Make a neat detailed sketch of the assembly.2.2 If the three strips are fastened together at 15 0C, determine the shear stress set up inthe rivets when the temperature is raised to 21 0C.Note: The resistance of a rivet in double shear may be taken as 1.75 times the resistancein single shear.(For steel: E = 200 GPa and α = 11×10 -6/ 0C)(For aluminium: E = 70 GPa and α = 22×10-6/0C)
