Guys I really need a lot of help on some engineering questions due tommorrow. If theres anyway your good at this topic pls coment or answer below so I can tell you the questions. Pls help a brodie out.. :(

The higher the astm grain size number, the finer the gran is. a)-true b)-false

Aquick transition of the operating speed of a shaft from its critical speed will whirl amplitude. (a) increase (b) limit (c) not affect (d) zero

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?
