Unformatted text preview: acting on a body is a stress tensor, stress field is the orientation of stresses in a body 11. problem 12. hydrostatic pressure is pressure that is equal on all sides 13. a 14. a 15. a 16. a 17. a 18. a 19. vectors require three coordinates to define it, 2 nd rank tensor require nine coordinates 20. Isotropic stress is when the three principal stresses are equal in magnitude, stress trajectories connecting the orientation of principal stress vectors at several points in a body, stress field collectively principal stress trajectories in a body, homogenous stress each point in field have same orientation, heterogeneous stress does not 21. hydrostatic pressure mean stress on a body, stressed equally in all directions...
