- Problem 1 50 Of Total Marks A Rod Consisting Of Two Cylindrical Portions Ab And Bc Is Restrained At Both Ends Portio 1 (108.08 KiB) Viewed 64 times
PROBLEM 1 (50% of total marks) A rod consisting of two cylindrical portions AB and BC is restrained at both ends. Portion AB is made of brass (Eb = 100 GPa, ab = 21 x 10-6/°C) and portion BC is made of aluminum (Ea 70 GPa, da = 24 x 10-6/°C). Knowing that the rod is initially unstressed, determine: (a) the normal stresses induced in portions AB and BC by a temperature rise of 45°C, (b) the corresponding deflection of point B.
