(si units) a low-carbon steel plate is 270 mm wide and 25 mm thick. a cluster mill with working rolls of radius = 600 mm is used, and roll speed = 30 m/min. it is reduced in one pass to a thickness of 20 mm. strength coefficient = 500 mpa, and strain hardening exponent = 0.25. determine (a) roll force, (b) roll torque, and (c) power required to perform the operation.

Burgers vector is generally parallel to the dislocation line. a)-true b)-false

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?
