1.5 m-Figure 2The -red-brass rod AB of 1.5 m and the aluminium rod BC of 1 m, shown in Figure 1,are joined at the collar B and fixed to the walls at their ends.If there is no intemal force in the members when the temperature T1 = 10°C,determine the average normal stress in each member when the temperaturerises to T2 50°C. Apply the sign conventions.Will the collar be displaced and if yes, how far will it be displaced and in whatdirection?The cross-sectional area of each member is 1000 mm?. The modulus of elasticity forbrass Eir = 100 GPa and for aluminum Eai = 70 GPa. The coefficient for thermalexpansion for brass is abr = 18(10)/°C, and for aluminum a.1 = 23(10)/°C.

A cylindrical pressure vessel is made by shrinking a brass shell over a mild steel shell. Both cylinders have a wall thickness of 6 mm. The nominal diameter of the vessel is 750 mm and is to be used in all calculations involving the diameter. When the brass cylinder is heated 50°C above room temperature, it exactly fits over the steel cylinder which is at room temperature. What is the stress in the brass cylinder when the composite vessels cool to room temperature?
