- A Rod Consisting Of Two Cylindrical Portions Ab And Bc Is Restrained At Both Ends As Shown In Figure Q1 Portion Ab Is M 1 (29.72 KiB) Viewed 27 times
A rod consisting of two cylindrical portions AB and BC is restrained at both ends as shown in Figure Q1. Portion AB is made up of steel (E, 200 GPa, as = 11.7 x 106 /°C) and portion BC is made of brass (Eb = 120 GPa, ab 18.7 x 106 /°C). Knowing that the rod is initially unstressed, determine (a) the normal stresses induced in portions AB and BC by temperature rise of 18 °C, and (15 marks) (b) the corresponding deflection of point B.
