Do intermediate calculations. give your final answer(s) to three significant fig. the electric a 500 n m torque on the aluminium that abcd when it is rotating at a constant speed. knowing the g = 26 gpa and that the torques exerted on the pulleys b and c are the shown, determine the angle of twist between b and d.

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?
