Transcribed Image Text:
In Figure Q2, tube AB is made from magnesium alloy and is fixed to the wall at its end A. The tube has a rigid plate welded to it on another end B. Another solid circular rod CD made from aluminium alloy, is fixed on the opposite wall such that the gap between the end cap B and end C is 0.2 mm. The existing environmental temperature is 30°C. If the temperature increases to 80°C, determine the normal stress-induced in the tube AB and the rod CD. Also, determine the highest temperature to which it can be raised without causing yielding either in the tube or the rod. The thickness of the rigid cap can be neglected. (Use thermal expansion coefficient amg = 26x106/°C, cal = 24x106/°C; Young's modulus Emg = 45 GPa, Eal = 69 GPa; Yield strength of tube AB and CD are 150 MPa and 250 MPa, respectively.)
