Physics · Mechanical Vibrations
In a damped forced vibration system, how does increasing the damping ratio (ζ) affect the force transmissibility Tr?
- 1Causes Tr to become infinite at all frequencies
- 2Always increases Tr for all frequency ratios r
- 3Makes Tr independent of damping ratio
- 4Reduces the peak transmissibility at resonance and increases Tr at high frequency ratios (r > √2)✓
Correct answer
Reduces the peak transmissibility at resonance and increases Tr at high frequency ratios (r > √2)
