Gaping

from Wikipedia, the free encyclopedia

In scientific and technical fields, a gap is the opening of a space ( gap ) or an unexpected discrepancy between two geometrical quantities.

Some examples of the use of this term are:

  • In cartography, the small difference in the corners of the map when several sheets of a map are put together. This gap (generally less than 1 mm) can be due to the map projection and / or to the paper input .
    • Your theoretical compartment is related to the inevitable distortion in the projection of the globe onto the plane, where the length of lines changes somewhat. On the other hand, it is independent of the geometrical sheet cut if it is carried out precisely enough.
    • The paper input, on the other hand, can be kept within practical limits (below about 2 mm) by choosing the type of paper .
  • In geology, a parting line, crevice or cleft between different rock bodies or formations . Common causes are frost blasting or a geological fault line (fossil or active geodynamics ).
  • In mechanical engineering or construction, when several components or workpieces can not be joined together precisely because the manufacturing tolerance is exceeded (for example when assembling a tank or in prefabricated construction )
  • in medicine, the distance between the edges of a wound or between the contact surfaces of a joint .
