Ungern

Thank you Milenium and 1963 maniac .

Hello everybody One technical question: We say that the first lego where made of wood I think that it was with a simple system of tenon and mortise so that the construction didn't can be reversed ,because the gravity would delete the construction. I don't no ...I ask What has been the next step ? A system of tenon and mortise in plastic only ?, or directly a system of tenon and mortise with a little distorsion of the mortise ? Now, how the system work ? tenon and mortise + little distorsion +little air vacuum? If there is a distorsion ...I dont know...I ask ... a) what is the amount of distorsion ?... I think that we are speaking here in "Angstöm" ? b) how many time can we do the same distorsion on the same block? c) how many time a distorsion can exist before appearance of a "memory problem with the plastic so that he couldn't be use "again" ?
