At the instant under consideration, the hydraulic cylinder AB has a length L = 1.40 m, and this length is momentarily increasing at a constant rate of 0.36 m/s. If vA = 0.55 m/s and θ = 39°, determine the velocity of slider B. The velocity of B is positive if upward, negative if downward.

Burgers vector is generally parallel to the dislocation line. a)-true b)-false

True or false (explain) (110)[111] is a slip system in bcc metals . the {111} family in fcc contains 8 planes. resolved shear stress (rss) in single crystals is just related to the applied stress. critical resolved shear stress (crss) in single crystal metals is direct proportional to the number of defects in the structure

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?
