Martin J. King — MathCAD worksheets (informative overview)
Martin J. King is known among engineering and applied-mathematics communities for creating and sharing Mathcad worksheets that demonstrate practical problem-solving, computational techniques, and worked examples across mechanics, dynamics, structural analysis, and numerical methods. Below is a concise, structured summary of the typical content, pedagogical value, and how to use and adapt such worksheets.
2. The Offset Driver Worksheet
In a standard TL, the driver is at the closed end. King provided specific worksheets to model placing the driver 1/3 or 1/2 down the line, which helps smooth out standing wave ripples.
Limitations and caveats
- Version compatibility: Mathcad Prime files may not open in legacy Mathcad and vice versa; features and syntax differ.
- Proprietary format: Mathcad worksheets are binary/proprietary and require Mathcad to edit; some content may be viewable as PDF only.
- Scale: Very large symbolic manipulations can be slow or limited compared to specialized CAS tools.
- Reproducibility: If worksheets rely on embedded fonts, custom images, or specific Mathcad features, exact reproduction may require the same environment.
Who is Martin J. King?
Martin J. King is a retired mechanical engineer with a background in vibration analysis. In the early 2000s, he turned his analytical eye toward a long-standing problem in audio: the transmission line (TL) loudspeaker. Unlike ported boxes (bass reflex) or sealed enclosures, transmission lines were considered "black art"—tricky to model, difficult to build, and heavily reliant on trial and error.
King’s contribution was to apply transmission line theory (often used in RF engineering and telecommunications) to low-frequency acoustics. He wrote extensively in the Audio Engineering Society (AES) and, crucially, released his work via Mathcad—a engineering calculation software that allows for mathematical notation, live solving, and data visualization.
Common application areas covered
- Statics and mechanics of materials (shear/moment diagrams, deflection)
- Structural analysis (matrix methods, stiffness matrices)
- Dynamics and vibrations (single- and multi-degree-of-freedom systems, modal analysis)
- Control systems (time- and frequency-domain simulation)
- Heat transfer and fluid flow examples (simple conduction/convection problems)
- Numerical methods (root finding, interpolation, numerical integration, eigenvalue solutions)
