Problem 1 Consider O, J, M, two second and third order tensors. a) Write O ij,j in cylindrical and spherical coordinates. b) Write O ij,j - Milk,jk in orthogonal curvilinear coordinates. Apply the formulas to the particular case of spherical coordinates. c) Assume divo + Vx(divJ)=0 and write this relation in cylindrical and spherical coordinates
