2 cards from this section. Quick, good the night before a test.
What is the purpose of the Response vs Frequency Ratio graph?
Think about what happens at resonance.
Define phase shift.
How do you measure time differences in waveforms?
What does the Response vs Frequency Ratio graph show?
Consider what 'response' refers to in this context.
True or False: A phase shift is irrelevant when tuning dynamic absorbers.
Think about how vibrations can either align or misalign with the input.
Given a system with a natural frequency of 2 Hz and a damping ratio of 0.1, calculate the response amplitude at a frequency ratio of 1.5.
Involve the dynamics of damped systems to estimate the response.
Explore how the phase shift changes from 0° to 180° as frequency increases. Create a hypothetical scenario where the phase shift impacts vibration isolation in a given system.
Think about how phase shifts would affect the reaction of a damper.
