Question 2.
List one application of 2-DOF systems in engineering.
Show hintHide hint
What type of building are you familiar with?
3Question 3.
What does a 2-DOF system require to describe its motion?
- One coordinate
- Two coordinates
- Three coordinates
Show hintHide hint
Focus on how many movements are needed to describe its behavior.
4Question 4.
True or False: Resonance is beneficial for structures during earthquakes.
- True
- False
Show hintHide hint
Think about how vibrations can intensify under certain conditions.
Question 5.
Consider a two-story building modeled as a 2-DOF system. If the first floor has a stiffness of 30000 N/m and the second floor 25000 N/m, calculate the effective stiffness and explain how this affects the overall building's dynamic response.
Show hintHide hint
Focus on how modifications in stiffness affect natural frequencies.
Question 6.
Analyze the effects of torsional coupling in an asymmetric building modeled as a 2-DOF system under earthquake loading. What are the implications for design?
Show hintHide hint
Think about how mass distribution influences torsion.
