WebHere to call certain components of the stresses as normal and others as shear, we have exploited the relationship between the components of the stress tensor and the traction vector. 4.4 Principal stresses and directions. At a given location in the body the magnitude of the normal and shear traction depend on the orientation of the plane. WebTension force tries to elongate the material. In contrast, compression attempts to shorten the body. 2. It pulls materials apart. It squeezes material together. 3. In tension, all forces are pulling away from the object. In compression, the forces acting on the material push towards the body. 4.
