A 400 mm long bar has rectangular cross-section 10 mm x 30 mm. This bar is subjected to (i) 15 kN tensile force on 10 mm x 30 mm faces, (ii) 80 kN compressive force on 10 mm x 400 mm faces, and (iii) 180 kN tensile force on 30 mm x 400 mm faces. Find the change in volume if E = 2 x 105 N/mm2 and u= 0.3.
