Advance (also called constantan) has a strain sensitivity sa=2.1 for strain as large as 8%. determine the amount of contribution due to the change in specific resistance to sa in the elastic region (poisson's ratio v=0.30) and plastic region (poisson's ratio v=0.30).

On solidification from a melt, the polymer polyethylene forms a semi-crystalline spherulite structure. (i) sketch an individual spherulite and label the amorphous and crystalline regions. (ii) draw a schematic to show the changes in specific volume with temperature during cooling from the melt, comparing it to the theoretical extremes of fully crystalline and fully amorphous (indicate tm and tg)
