The stepped rod is made up of two different materials A and B of lengths 80 cm and 1.2 m respectively. The diameters of materials B and A are 2.5 and 3.5 cm respectively. The modulus of elasticity of materials A and B are 250 and 150 GPa respectively. The elongation of the rod is the same for both the materials. A total tensile load of 40 kN is applied to both the materials A and B together. Calculate the load in each material.
