Two solid vertical cylindrical rods \( A B \) and \( B C \) made of two different materials are welded together at \( B \) and hang down from a fixed support at \( C \) as shown below. End \( A \) is free, a vertically upward force of \( 43.5 \mathrm{kip} \) acts at \( B \), and the weights of the rods can be neglected. The lengths, areas of cross-section, and moduli of elasticity of the two rods are given on the figure Determine the magnitude of the axial deformation at end \( A \) and enter it in in. (inches) correct to 3 significant digits below. Note that the magnitude of axial deformation should be a positive number.
