Conversely, if this condition be satisfied, an infinitesimal deformation is possible.
Many forms of deformation, it may be remarked in passing, emphasize some natural physical characteristic of the people who practise them.
In any infinitely small deformation of the frame as thus modified, the virtual work of the forces 5, together with that of the original extraneous forces, must ~ranish this determines S.
Strains exceeding the "limit of elasticity" result in permanent deformation or (if sufficiently great) in rupture.
The accidental use of a single name, America, for the pair of continents that has a greater extension from north to south than any other continuous land area of the globe, has had some recent justification, since the small body of geological opinion has turned in favour of the theory of the tetrahedral deformation of the earth's crust as affording explanation of the grouping of continents and oceans.
