A 3-mm-diameter cord (E 7 GPa) that is covered with a 0.5-mm thick plastic sheath (E = 14 GPa) is subjected to an axial tensile load P, as shown in Fig. P5-36. The load is trans- ferred to the cord and sheath by rigid blocks attached to the ends of the assembly. The length of the cord-sheath assembly is 500 mm and the load Pis 90 N. Determine the forces carried by the cord and sheath.
