Calculate the efficiency of a hydrogen production system for a future transportation alternative for the cases of: 1. A nuclear system using the Steam Cycle with an overall thermal efficiency of 33.3 percent, 2. A nuclear system using the Brayton Gas Turbine Cycle with an overall thermal efficiency of 60 percent.

Plot schematically the tensile stress versus strain curves for a typical thermoplastic material at a temperature below its glass transition temperature (tg and at a temperature above its tg, respectively. do the same for a typical thermosetting material. list in a table any differences or similarities between the two materials at t> tg and t < tg, respectively, and relate them to the structures of the two types of polymers
