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)

You are to evaluate the feasibility of a cencrete infill in a hollow structural steel section subjected only to pure berding Specifically, you are tasked to determine if there will be an increase in the bending mament capacity from a hollow structural square steel section with the following dimensions shown to a concrele filled steel tube 6 mm 100 mm Material Properties: Yield stress af Steet fy, steel - 420MPa Etaul = 200G Pa Maximum compressive strength of Concrete: fe = 27M Pa Eurede = 4700VT.(e und Eanerate in MPa Under elastic stress analysis, the stress distribution within the concrete filed steel tube is as follows, NA o, - EE, Steel Stress Concrete below the NA Is not considered for analysis Concrete Stress Distribution Distribution This stress distribution is for the untransformed cross section. Moreover, since concrele carry little to na tensile stresses, the portion of the concrete below the neutral axis which resist tensile stresses will nat be considered in the anahlysis…
Assuming the concrete is uncracked, compute the flexure stresses in the extreme fibers of the beam as shown in the figure for a bending moment of 34 kN-m. The concrete has an f' of 27.60 MPa; determine also the cracking moment of the section. (Use 0.62 1 = 0.70 in calculating the modulus of rupture).
