Beams · gears · stack-up · weld

Extra beam cases, spur-gear mesh, worst-case vs RSS tolerance, a motor curve you typed, AWS-style weld cards, and fasteners beyond tap drills.

Euler–Bernoulli, ideal mesh, handbook weld names. Not FEA, not a WPS, not a mill cert.

Section

I = bh³/12 = 4.166667e-6 m⁴

Three cases

  • Center load: δ 0.0002 m · M 500 N·m
  • Cantilever end: δ 0.0032 m · M 2000 N·m
  • UDL simply supported: δ 1.000000e-4 m · M 200 N·m

Small deflection, linear E, one load case. Not a stamp.
