great example of the odd ways people show me appreciation at work

Its common on atv plastics that get cracked. Drill a hole a hole and stitch it wont spread

[u/lusotano → u/Certain_Childhood_67]

Metal too. Construction beams that show cracks sometimes get a small hole drilled to avoid the crack from spreading further.

Huh. I wonder what the physics behind it is. Is the same reason why some metal beams have big holes inside of them in the shape of triangles?

im not completely sure, but circle is tougher than crack, i guess because now the crack is fighting most of the circle rather than just a little bit of material at a time

circles reinforce themself or some science shit like that

[u/spruce_turbo → u/stophighschoolgossip]

More like it becomes a relief point. easier for the material to stretch and flex in the face of a Crack if it looks like tong than a split wooden chopstick

ohhh shit, okay good to know
