True
False
The steady-state response of a vibrating system is found by determining __________ of the differential equation
The homogeneous solution
The particular solution
The characteristic equation
Both the homogeneous and particular solutions
The force transmitted in a forced damped system can be found through scalar addition of the damper and spring forces
True
False
A damper is added to a simple forced spring-mass system.
Select ALL that are true
The natural frequency would change
Amplitude of response decreases
Transmissibility decreases
Static deflection decreases
If a damper is added to a previously undamped base excitation system, the transmissibility at an operating speed of
pω=2Increases
Decreases
Stays the same
Insufficient information
Transient vibrations are always greater in amplitude than steady-state vibrations
True
False
The transient response to a non-periodic load (i.e. a step load) will have no impact on the steady-state response in a system.
True
False
Initial conditions can be ignored if there is an impulse or step load present
True
False
