1.5 m- Figure 2 The -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 temperature rises to T2 50°C. Apply the sign conventions. Will the collar be displaced and if yes, how far will it be displaced and in what direction? The cross-sectional area of each member is 1000 mm?. The modulus of elasticity for brass Eir = 100 GPa and for aluminum Eai = 70 GPa. The coefficient for thermal expansion 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.
