The mystery of the broken wrench

[RandomTroll]

@George_San_Jose1

just trying to understand where the 3/16 comes

My measurement of the wrench.

@texases

I haves couple of oddball 32nd wrenches, never used

Why’d you get them?

@jtsanders

Look at the sides of the wrench at the break. Do you see any damage, like a dent or gouge?

No.

@jtsanders

look at the fracture face if it’s still undamaged. There might be discontinuities, like big inclusions or internal cracks that weren’t visible before the wrench broke.

I don’t see them. The broken face is jagged; it looks like enough force was applied to make it break. I’ve made smaller pieces of steel break; I can imagine the shock I’d get from breaking something this thick.
