⚙️ Engineering Calculations

The application uses standard beam theory equations for a simply supported rectangular beam.

Center Point Load

Maximum bending moment:

Mmax = P × L / 4

Maximum deflection:

δmax = P × L³ / (48 × E × I)

Full-Span UDL

Maximum bending moment:

Mmax = w × L² / 8

Maximum deflection:

δmax = 5 × w × L⁴ / (384 × E × I)

Bending Stress

σmax = Mmax × c / I

Factor of Safety

FOS = Yield Strength / Maximum Bending Stress
