Volume and dilation in the normal road windows in axial way

If a structural element, in this case the rod, loaded by a reduction in the focus section poprečenog optrerećenje limited to axial forces, then we say that the element is exposed to stress aksionalnom. In this case askijalna force may be the resultant of force systems whose direction coincides with the axis of the rod and at the same time it is called elongation or compression axial load.
