Question 1.
What is the formula for undamped natural frequency in an SDOF system?
Show hintHide hint
Consider how mass and stiffness relate to frequency.
Question 2.
What are the main components of a mass-spring-damper system?
Show hintHide hint
Think about what each component represents in vibration analysis.
3Question 3.
What does the abbreviation SDOF stand for?
- Single Degree of Freedom
- Simple Degree of Freedom
- Special Degree of Freedom
Show hintHide hint
Think about systems that can only move back and forth.
4Question 4.
True or false: Higher mass leads to a higher natural frequency in SDOF systems.
- True
- False
Show hintHide hint
Recall the formula and how each component behaves.
Question 5.
Consider a mass-spring-damper system with a mass of 5 kg and a spring constant of 200 N/m. Calculate the undamped natural frequency.
Show hintHide hint
Use the formula for natural frequency.
Question 6.
Design a simple SDOF model for a building with a mass of 1500 kg and a stiffness of 60000 N/m. What is the natural frequency, and what does it imply for earthquake resistance?
Show hintHide hint
Insert your parameters into the natural frequency formula.
