Assume that the axial member is in equilibrium and the applied forces are an unknown load F1, F2 = 14 kN , F3 = 12 kN , and F4 = 8 kN . Calculate the internal resultant normal force at section D. Express your answers to three significant figures in kN. View Available Hint(s)

Afluid flows with a velocity field given by v=(x/t)i.. determine the local and convective accelerations when x=3 and t=1.

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
