Given the following system, with values of jo = 8 kg-m2, k = 15 kn/m, l= 2.5 m, c1 = 50 n-s/m and c2 = 18 n-s/m. using lagrange equation, find the ceqin 2 decimal points, according to the rayleigh’s dissipation function.

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
