4 cards from this section. Quick, good the night before a test.
Define damping in your own words.
Think about energy loss during vibrations.
What is the definition of an undamped system?
Focus on what happens to the amplitude over time.
What effect does damping have on a vibrational system?
Consider how real structures behave compared to ideal systems.
True or False: An undamped system will eventually stop oscillating.
Focus on the behavior of undamped systems.
A structure designed to withstand seismic forces has a natural frequency of 1 Hz. If the system incorporates a damper with a damping coefficient of 10 Ns/m, what is the damping ratio if its mass is 50 kg and stiffness is 250 N/m?
Ensure all variables are identified clearly prior to calculation.
Evaluate how introducing a damping coefficient affects the oscillation period of a system with mass 15 kg and stiffness 300 N/m.
Remember that putting in damping changes oscillation behavior slightly but primarily affects decay of amplitude.
