You worked on Earthquake Engineering Design Challenge during the last three parts. Please upload your S. T.E. M. Lab Earthquake Engineering Design Challenge worksheet. Make sure that you have answered all parts for Steps 1–13 and your work is shown on the worksheet and double-check your work. When you are sure that you have answered all of the Steps accurately, please upload your worksheet.

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?
