Quick Start

import phaxor

# ─── Ideal Gas Law ───────────────────────────────────────────
result = phaxor.compute('ideal-gas', {
    'solveFor': 'pressure',
    'volume': 0.02241, 'moles': 1, 'temperature': 273.15
})
print(f"Pressure = {result['P']:.0f} Pa")  # 101325 Pa

# ─── Ohm's Law ──────────────────────────────────────────────
result = phaxor.compute('ohms-law', {
    'solveFor': 'I', 'voltage': 12, 'resistance': 100
})
print(f"Current = {result['I']} A")  # 0.12 A

# ─── Mohr's Circle ──────────────────────────────────────────
result = phaxor.compute('mohrs-circle', {
    'sigmaX': 80, 'sigmaY': -40, 'tauXY': 30
})
print(f"σ₁ = {result['sigma1']:.1f} MPa")

# ─── Unit Conversion ────────────────────────────────────────
km = phaxor.convert('length', 1, 'mi', 'km')
print(f"1 mile = {km:.6f} km")

# ─── List all calculators ───────────────────────────────────
for calc in phaxor.list_calculators():
    print(f"  {calc['id']:24s} {calc['name']}")

phaxor.plot.beam_diagram(
    length=6000,
    point_loads=[
        {'position': 2000, 'magnitude': 15, 'direction': 'down'},
        {'position': 4000, 'magnitude': 10, 'direction': 'down'},

# Compare any calculator across scenarios
phaxor.plot.compare('ohms-law',
    [{'solveFor': 'P', 'voltage': 12, 'resistance': r} for r in [10, 50, 100, 500]],

Materials Database (phaxor.materials)

Basic edition includes 20 curated materials. For the full 1,550+ material database, use the Cloud API.

import phaxor

# Look up a material
mat = phaxor.materials.get_material('steel-a36')
print(f"E = {mat['E']} GPa, σy = {mat['sigmaY']} MPa")

# List all available materials
for m in phaxor.materials.list_materials():
    print(f"  {m['id']:20s} {m['name']:30s} [{m['category']}]")

# Filter by category
metals = phaxor.materials.list_materials('metals')

# Compare materials side-by-side
comparison = phaxor.materials.compare_materials('steel-a36', 'aluminum-6061', 'titanium-ti6al4v')

Available materials (free library):

Category	Count	Materials
Metals	10	A36, A572, SS304, SS316, Al-6061, Al-7075, Copper, Ti-6Al-4V, Cast Iron, Inconel 625
Polymers	5	ABS, Nylon 6, HDPE, PVC, PEEK
Concrete	3	M20, M30, M40

Studio Tools (phaxor.studio)

Simplified engineering tools for learning. For the full interactive studios, use the Cloud API.

import phaxor

# Failure analysis against multiple theories
result = phaxor.studio.check_failure(
    sigma_x=180, sigma_y=-60, tau_xy=45,
    sigma_yield=250, theory='all'
)
for name, theory in result['theories'].items():
    print(f"  {name}: FoS = {theory['factorOfSafety']:.2f} — {theory['status']}")

# Manufacturing cost estimation
cost = phaxor.studio.estimate_cost(
    material='aluminum-6061', volume_m3=0.0005,
    process='machining', quantity=100
)
print(f"Unit cost: ${cost['unitCost']} → Total: ${cost['totalCost']}")

# Find materials matching requirements
matches = phaxor.studio.find_material(min_yield=300, max_density=5000)
for m in matches:
    print(f"  {m['name']:25s} σy={m['sigmaY']} MPa, ρ={m['density']} kg/m³")

# Section properties
props = phaxor.studio.section_properties('i-beam', bf=200, tf=15, hw=300, tw=10)
print(f"Area = {props['area']} mm², Ix = {props['Ix']} mm⁴")

# Quick design check
check = phaxor.studio.design_check(load=50000, area=500, material='steel-a36')
print(check['statusText'])

Jupyter Notebooks

In Jupyter, compute() automatically renders styled HTML tables:

import phaxor

phaxor.compute('ideal-gas', {
    'solveFor': 'pressure',
    'volume': 0.02241, 'moles': 1, 'temperature': 273.15
})
# → Renders a styled table with results
