SUMMARY
The discussion centers on the transmissibility ratio (T.R.) in vibration analysis, specifically addressing the conditions under which positive or negative roots are taken when damping is zero. The transmissibility ratio is defined as a ratio of force magnitudes and is typically considered positive. The negative root is applicable when the ratio of natural frequency to excitation frequency (r) exceeds one (r > 1). The variable r represents the relationship between natural frequency (ωn) and excitation frequency (ω), indicating proximity to the resonant frequency without direct implications for damping.
