Holes gather
Stress comes to the narrow door.
Name the gather
0/4
A hole, a notch, a sharp inner corner. Stress gathers.
A round that calms the gather.
The body’s own mass as a load. Long bars feel it first.

CheckA sharp inner corner is a quiet thief. Round it. Find the raiser. Fillet. Name self-weight. Extra support needs stretch.
