Engineering Insights

If you've ever lived in an apartment and wondered why you can hear your neighbor's TV through the wall - or marveled at how quiet a recording studio is - you've already got an intuitive sense of sound transmission loss. The physics behind it are surprisingly elegant, and the centerpiece is something called the Mass Law.

A systematic framework for selecting accelerometers, DAQ systems, and signal conditioning for modal testing, acoustic testing, vibration qualification, shock testing, and pyroshock environments. Includes comparison tables, checklists, and decision flowcharts.

Ground Vibration Testing (GVT) represents one of the most critical milestones in aircraft development, serving as the essential bridge between analytical predictions and flight safety. Learn about excitation methods, instrumentation requirements, frequency ranges, and how GVT results drive flutter analysis and certification.

Understanding Max Q is essential for predicting fluctuating pressure environments and sizing structural components in early vehicle design. This post covers the physics, vehicle class behavior, and how to use the FSP Tool for aeroacoustic analysis.

Master the fundamentals of structural engineering with this comprehensive guide covering static equilibrium, free-body diagrams, internal forces, load paths, wing deflection analysis for different maneuver conditions, and spar orientation effects on stiffness. Essential knowledge for conceptual design work and design reviews.

The SDOF system is the cornerstone of structural dynamics. This comprehensive tutorial covers the equation of motion, key parameters, free and forced vibration, transmissibility, and practical applications.
