Question: a rod consisting of two cylindrical portions ab and bc...

Question details

A rod consisting of two cylindrical portions AB and BC is restrained at both ends. Portion AB is made of steel (Es-200 GPa,as-117s į0-6PC) and portion BC is made of brass ( Eb 105 GPa, a, -20.9x 106/°c). Knowing that the rod is initially unstressed, determine the compressive force induced inABC when there is a temperature rise of 57°C. 29-mm diameter 150 mm 53-mm diameter 320 mm
