3.A 150 mm diameter cast iron (E = 99 GPa, ν = 0.211) wheel, 50 mm wide, rolls on a flat steel plate (E = 207 GPa, ν = 0.292), and carries a load of 3.6 kN. Determine the maximum shear stress at a depth of 0.38 mm in the wheel

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

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
