Question 1.
What is an SDOF system?
Show hintHide hint
Think of a simple mass on a spring.
Question 2.
What does an MDOF system represent?
Show hintHide hint
Consider a structure like a multi-story building.
3Question 3.
What defines a Single Degree of Freedom (SDOF) system?
- It requires one coordinate to describe motion
- It requires two coordinates
- It has infinite degrees of freedom
Show hintHide hint
Think of how many coordinates are needed for a simple model.
4Question 4.
True or False: MDOF systems can model complex structures more accurately than SDOF systems.
- True
- False
Show hintHide hint
Consider the level of detail in each system.
Question 5.
For a system modeled as SDOF, describe the approach to analyze its vibration under a single periodic force.
Show hintHide hint
Think about how the natural frequency plays a role in the response.
Question 6.
Discuss the implications of assuming an MDOF system as an SDOF system for large buildings during earthquakes.
Show hintHide hint
Consider how energy might transfer through different parts of the building.
