Acold-drawn aisi 1015 steel tube is 300 mm od by 200 mm id and is to be subjected to an external pressure caused by a shrink fit. what maximum pressure would cause the material of the tube to yield? . syt = syc = 600 mpa.

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?
