Under eccentric loading on the cross section below, where a load P acts along the +x axis at a location of z = -2, y = +6 relative to the defined axis, determine the location and value of the maximum tensile and maximum compressive stress. Include identification of which is in compression and which is in tension.
h = 10in
w = 5 in
P = 5 kip

Describe one experiment in which the glass transition temperature and melting temperature of a totally amorphous thermoplastic material can be determined. show the relevant experimental results in a diagram which should be properly annotated with the two temperatures clearly marked. what is likely to happen to the curve in the diagram if the amorphous polymer is replaced by a thermosetting type?
