A steel rod 32 mm in diameter is fixed concentrically in a brass tube which has outside and inside diameters of 48 mm and 34 mm respectively. Both the rod and tube are 40 cm long and their ends are levelled. The compound rod is held between two supports which are exactly 40 cm apart and the temperature of compound bar is then raised by 60°C. What will be stress in the brass tube (in kg/cm2) if the distance between the supports in increased by 0.025 cm? Take Es = 2 x 106 kg/cm2, E, = 0.9 x 106 kg/cm2, as = 12 x 10-6/°C, a, = 21 x 10-6/°C

4.20. A copper tube 55 mm in outside diameter and of wall thickness 5 mm fits loosely over a solid steel circular bar 40 mm in diameter. The two members are fastened together by two metal pins each 8 mm in diameter and passing transversely through both members, one pin being near each end of the assembly. At room temperature the assembly is stress free when the pins are in position. The temperature of the entire assembly is then raised 40°C. Calculate the average shear stress in the pins. For copper E = 90 GPa, a = 18×10 °C; for steel E200 GPa, a 12 x 10 *°C. Ans. 132 MPa
