At room temperature (20 degrees C) a 0.5-mm gap exists betweenthe ends of the rods shown. At a later time when

thetemperature has reached 140 degrees C determine (a) the

normalstress in the aluminum rod, (b) the change in lenth of the

aluminumrod.

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
