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...
