Aload of 1 kg is applied to the tip of a cantilever beam with a width b = 2.5 cm, a thickness h = 1 mm, length l = 20 cm, modulus e = 74 gpa, and density 2.7 g/cm3. what strain is experienced on the bottom surface of the strain gauge 5 cm from the fixed end?

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?
