free vibration, stiffness and flexibility Flashcards
(5 cards)
1
Q
what is resonant frequency?
A
The frequency at which a force/torque should be applied so as to make a vibration’s amplitude increase significantly.
2
Q
what is stiffness?
A
Extent to which something resists deformation when a load is applied.
3
Q
what is flexibility?
A
is measure of how much something deforms in response to an applied load.
4
Q
why are resonant frequencies to be avoided in many applications?
A
it can cause buildings to move around.
5
