Summary
[edit]Description50naegel-nagelprobe-magicnails-berchtesgadener.jpg |
English: A mindbending mechanical puzzle or logical puzzle. A medium to huge amount of carpenter-nails shall be placed on top of exactly one single nail that is allowed to stick or be hit the ground or some block of wood. All other nails must be balancing on top of the first. Here you see 50 carpenter-nails in whole.
Deutsch: Ein schweres mechanisches Geduldsspiel (typische Bezeichnungen sind Nagelprobe, magische Nägel, Head of Nails, auch Berchtesgadener Problem). Eine mittlere oder größere Anzahl an Zimmermannsnägeln müssen auf exakt einem Nagelkopf balanciert werden. Dieser ist als einziger Nagel im Boden oder in einem Holzblock eingeschlagen. Hier sind bereits 50 Zimmermannsnägel verwendet. |

- ...if the nails are balancing pairwise the amount of balancing nails must be a even number in total. Or...
- The pairwise placing of the nails as in Image:Lösung_BerchtesgadenerProblem.JPG seems to limit the amount of total nails since the length of the both nails carrying the others is limited as well.
- ... durch das paarweise Balancieren der Nägel auch eine gerade Anzahl balancierender Nägel Pflicht ist. Oder dass...
- ... die paarweise Anordnung der Nägel wie in Image:Lösung_BerchtesgadenerProblem.JPG auf den beiden tragenden Nägeln fester Länge die Gesamtzahl der möglichen Nägel limitiert. Weitere müssten ja von dem Nagelpaar herabfallen.
