Transverse beam shear stress API

Computes average shear stress V/A and the peak shear stress at the neutral axis using the shape factor (1.5 rectangle, 4/3 solid circle, 2 thin tube), so an agent doesn't confuse average vs maximum. Answers 'What is the max shear stress in a beam?', 'What is the shape factor for shear?'.

  "shape": "rectangle"
}

Example response

{
  "shearForceN": 9000,
  "areaM2": 0.006,
  "shape": "rectangle",
  "peakFactor": 1.5,
  "averageShearStressPa": 1500000,
  "averageShearStressMPa": 1.5,
  "maxShearStressPa": 2250000,
  "maxShearStressMPa": 2.25,
  "formula": "τ_avg = V/A; τ_max = k*V/A (k: rect 1.5, circle 4/3, thin-tube 2)",
  "interpretation": "τ_max occurs at the neutral axis; use it, not the average, for shear checks."
