Mathematics · Mechanical Vibrations
A linear spring-mass-dashpot system with a mass of 2 kg undergoes viscous damped free vibration. If the natural frequency is 15 Hz, and the amplitudes of two successive cycles measured are 7.75 mm and 7.20 mm, the coefficient of viscous damping (in N·s/m) is approximately:
- 17.51
- 22.52
- 36.11
- 44.41✓
Correct answer
4.41
