The 50-lb plate ABCD is attached at A and D to collars that can slide on the vertical rod. Knowing that the coefficient of static friction is
0.4 between both collars and the rod, determine whether the plate is
in equilibrium in the position shown when the magmitude of the
vertical force applied at E is 20-lb:
a) The plate is in equilibrium
b) The plate is not in equilibrium

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?
