Wêrom is it hexagonal, net oars?
In protte minsken sille hawwe sa'n fraach, wêrom moat de bout wurde ûntwurpen yn in hexagonal foarm?En oaren net?Hexagon is it produkt fan kompromis tusken kant lingte en twist hoeke.
Foar bouten mei ûneven kant lingte, de twa kanten fan de wrench binne net parallel.Dêrnjonken wiene d'r yn 'e iere dagen allinich forkearde wrenches, en de measte fan' e wrench-koppen wiene trompetfoarmige, dus wrenches wiene net geskikt foar enerzjyopwekking.Derneist is de draaihoek ek in wichtige faktor om te beskôgjen.As it in fjouwer hoeke is, moat de wrench 90 graden draaid wurde om de skroeven te befestigjen, wat ûngeunstich is foar ynstallaasje yn in smelle romte;As it is achtkantich of decagonal, hoewol't de draaiende hoek wurdt lytser, de krêft is ek lyts, en it is maklik om te rûnen.
Dêrom is hexagon foarm in mienskiplike kar foar bouten.
