Question

Two aluminium strips are rigidly fixed to a steel strip of section 25mm × 8mm and 1m long. The aluminium strips are 0.5 m long each with section 25mm × 5mm. The composite bar is subjected to a tensile force of 10kN as shown in Fig. 2.10. Determine the deflection of point B. 

E_s = 3EA = 210 kN/mm².

Answer 1

AC is a composite bar and CB is a single steel bar of section 25 mm × 8 mm Portion CB
