Question 1.
What is the definition of natural frequency?
Show hintHide hint
Think about how things vibrate on their own.
Question 2.
What factors influence natural frequency?
Show hintHide hint
Consider the structure's weight and material stiffness.
3Question 3.
What is the natural frequency of a system?
- The rate of oscillation with external force
- The rate of oscillation without external forces
- The frequency of applied loads
Show hintHide hint
Remember, it is about the system’s inherent properties.
4Question 4.
