A round steel bar with a 1-inch diameter has known SuandSywithmachined surfaces. For (a) bending, (b) axial, and (c) torsional loading, determine the fatigue strength corresponding to (1) 106or more cycles and (2

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?
