(a) H(ω) = 4×104(60+j6ω) (4+j2ω)(100+j2ω)(400+j4ω) (b) H(ω) = (1+j0.2ω)2(100+j2ω)2 (jω)3(500+jω) (c) H(ω) = 8×10−2(10+j10ω) jω(16−ω2 +j4ω) (d) H(ω) = 4×104ω2(100−ω2 +j50ω) (5+j5ω)(200+j2ω)3

Draw the engineering stress-strain curve for (a) bcc; (b) fcc metals and mark important points.

Asolid cylinder is concentric with a straight pipe. the cylinder is 0.5 m long and has an outside diameter of 8 cm. the pipe has an inside diameter of 8.5 cm. the annulus between the cylinder ad the pipe contains stationary oil. the oil has a specific gravity of 0.92 and a kinematic viscosity of 5.57 x 10-4 m2/s. most nearly, what is the force needed to move the cylinder along the pipe at a constant velocity of 1 m/s?

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?
