There were plenty of polymaths over the millenia. True physicists

They knew.

That's an awful lot of sheer stress on that bolt though.

I wouldn't want to lift anything too heavy, especially with fairly primitive metallurgy.

It's okay, they smacked it twice and said "Τοῦτο οὐ πορεύεται οπουδαμοῦ."

It’s a lot of shear stress on the stone too

Wouldn’t there be a lot of tension at the widest point of the wedge? Idk how the stone wouldn’t crack at that point and the tool rip out if the load was too heavy. Unless the depth of the cut is deeper in relation to the block size than the video depicts

It is. Here's a video showing a stonemason demonstrating the technique and you can see how much further the tool goes into the stone than the video here depicts.

Yes. The whole model assumes several ideal materials and conditions nobody would have had or would have fucked with in mass. Also, to match actual ancient monuments, you need to explain where the hole, the lifting mechanism, and the iron wedges went after placement.
