1 4.75 m P While supporting load P, the maximum contraction permitted in a 4.75-m long pipe column is 5 mm. Given that E = 150.00 GPa for the column, determine the stress in the pipe at the maximum allowable contraction. State your answer in 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?
