🌉 Medieval Block Engineer: Arches, Bridges and Windmill Gears

Build a stone arch from nine wedges, remove the centering and load-test it with sacks of grain; see why a flat lintel cracks first, brace a half-timber frame and gear a windmill up to a millstone. Real thrust-line, bending, racking and gear-ratio maths.

⚙ Under the hood

Lay a stone arch from wedge blocks, take away the centering and load-test it with sacks of grain; see why a flat lintel cracks first, brace a half-timber frame against the wind and gear a windmill up to a millstone. Real thrust-line, bending, racking and gear-ratio maths.
