A 2 HP motor is attached to a gearbox by a coupling. The motor shaft (and therefore the input shaft of the gearbox) turns at 1,800 revolutions per minute. We observe that the output shaft of the gearbox is turning at 60 revolutions per minute, and is producing 1 HP of unusable power. From this data, we can conclude that the efficiency of the gearbox is:

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?
