A solid cylindrical steel rod is made from three portions as shown in Fig Q5b. It is subjected to a tensile axial load P. Knowing that the modulus of elasticity, E = 200 GPa, determine (a) the value of the load P so that the total deformation is 0.05 mm, and (b) the deformation of the central portion of the rod BC. [Ans. (a) 41.5 kN (b) 0.0317 mm]
