10–25. The 45° strain rosette is mounted on the surface of a shell. The following readings are obtained for each gage: ε a = −200(10−6), ε b = 300(10−6), and ε c = 250(10−6). Determine the in-plane principal strains.

For each of the following process: a) sketch the p-v diagram, b)sketch t-s diagram, c) sketch t-v diagram, d) sketch the boundary work on one of the diagrams (a, b or c) and e) sketch the reversible heat transfer on one of the diagrams (a, b or c): 1- isobaric process from compressed liquid to superheated vapor 2- isothermal process from compressed liquid to superheated vapor 3- isentropic process from compressed liquid to superheated vapor
