The coefficient of friction between block b and block a aremu s=0.12 and mu k=0.10 and thecoefficient of friction between block a and the incline aremu s=0.24 and mu k=0.20. themasses of block a and block b are 10 kg and 5 kgrespectively. knowing that the system is released from restin the position shownm dtermine (a) the acceleration of a, (b) thevelocity of b relative to a at t=0.5s.

Assuming compressible flow of air and that the measurements are done at flagstaff a pitot static tube that gives the difference of total and static pressure measures 0.35 m of mercury. what is the velocity of air? assume the temperature to be 300k. (submit your excel or matlab calculation sheet)

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
