A stepped bar made of steel, copper, and brass is under axial force as shown in figure, and is in equilibrium. The diameter of steel is 12mm, the diameter of copper is 16mm and the diameter of brass is 20mm. Determine (i) the Magnitude of unknown force P (ii) stresses in each material and (iii) the Total change in length of the bar. Take Esteel = 200GPa, Ecopper 100GPa and Ebrass = 80GPa 20 KN Steel 8 KN 1200 mm Copper 1100 mm * Brass 6 KN 1300 mm -PKN A stepped bar made of steel, copper, and brass is under axial force as shown in figure, and is in equilibrium.
