Along and narrow rectangular plate carries a non uniform loading p = p0 sin (πy/b) and is clamped at edges y = 0 and y = b. (a) derive an expression for the deflection surface w. (b) determine the maximum deflection and maximum strain. (c) find the radius of curvature at y = b/3 by taking b = 0.6 m, t = 15 mm, e = 200 gpa, ν = 1/3, and pp0 = 50 kpa. (hint: =)) 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?
