Materials Science and Engineering
Ch. 1: Paddle wheel drive shaft — choosing a steel and reading a stress-strain curve
Hibbeler's torsion chapter needs an allowable shear stress that doesn't come from a wood table — this is the first MM build in either guide asking a materials question instead of a structural one.
Ch. 2: Reading a strength number — using the published geopolymer range as a working stand-in
Rather than let the Snawfus/Uktena/Ogua chapters sit on "TBD" forever, this uses the published geopolymer literature range to land on a working stand-in of ~900 psi — provisional, and a triage tool for what to test first.
Ch. 3: Ceramics — why geopolymer breaks the way it does
The Uktena and Ogua chapters both landed on "grout the channels solid" as a rule — this is where that rule comes from, and why a moon-eye brick behaves nothing like a steel beam.
Ch. 4: Composites — why the rebar-in-brick system works as one material, not two
A composite only works if its parts are bonded well enough to share load — an ungrouted rebar channel isn't a composite, it's two materials near each other, and papercrete is a composite by a different mechanism entirely.
Ch. 5: Heat — how far things grow, and what happens when you don't let them
A 10-foot steel member heated 300°F grows about a quarter inch. Lock it in place and it tries to push with enough force to pass its own yield strength at only about 190°F. This chapter is the numbers behind leaving room to move.
Still unused, and what's waiting for it
- Metal alloys and corrosion: Held until the foundry's cast pieces start doing load-bearing work rather than decorative — no real build to anchor it to yet
