V to an axial pull of 45 KN. Take E for 2. A compound bar consists of a circular rod of steel of diameter 20 mm rigidly fitted tube of internal diameter of 20 mm and external diameter of 30 mm. If the composite bari mm long and is subjected to a compressive load of 30 kN, find the stresses developed and th steel rod and copper tube. Take Er = 200 GPa and E = 100 GPa. Also find the change length of the bar [Ans. 58.8 MPa, 29.4 MPa, 0.22 3. A uniform rigid block weighing 160 KN is to be supported on three bars as shown in Fig. and 160 KN 2 m Steel Aluminium A = 20 x 20 A = 25 x 25 2.5 m Aluminium A = 20 x 20 NIN INNESS I Fig. 5.24 There is 4 mm gap between the block and the top of the steel bar. Find the stresses develope the bars. Take Es = 200 GPa and EA = 80 GPa. [Ans. A = 148.9 MPa ; Os = 65.3 M . Stresses in Nuts and Bolts А 148.9 B 156.8
