Consider a stainless steel material with a brinnel hardness of 270, that is turned on a lathe. the undeformed chip thickness is 0.25 mm, and the cutting speed is 0.6 m/s. the chip is continuous and a 1- m-long section weighs 5.7 g. the chip width is the same as the workpiece width and equals 1.5 mm. calculate the cutting ratio. assume the density of the stainless steel is 8027 kg/m^3.

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?
