If an object is in the steady air (not wind) is it subject to an aerodynamic force?

The temperature of air decreases as it is compressed by an adiabatic compressor. a)- true b)- false

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
