How does a nail hold two things together? How doesn’t it not fall back out of the hole it created over time?
In: Engineering
That is a cool manufacturing question!
It’s known as an interference fit – sometimes known as force fit or friction fit. Essentially in intense friction between the material and the nail holds the piece in place to the nail.
Other forms of fits are Clearance & Transition. Clearance being minimal friction while Transition being the goldilocks of not too much but not too little friction.
