Read the problem statement carefully. If the input variable changes with time (e.g., "a sudden blast pressure of 500 psi is applied"), apply dynamic differential equations. If the problem involves fixed calibration points or uncertainty propagation, use static statistical models. Step 2: Establish the Transfer Function
These involve mass, spring compliance, and damping (e.g., accelerometers and pressure transducers). Their response depends heavily on the natural frequency ( ωnomega sub n ) and the damping ratio (
