Question 1

What does α < 0 indicate about a structural system?

  • Vibrations are increasing
  • The structure is stable
  • The structure is collapsing

💡 Hint: Remember how stability relates to vibration dampening.

Question 2

True or False: An unstable system is one where α < 0.

  • True
  • False

💡 Hint: Think about the consequences of instability in structural design.

Challenge Problems

Push your limits with challenges.

Question 1

Analyze a structure subjected to dynamic loads. If the discovered roots of the system are complex with α = -3 and β = 5, describe the behavior and stability of this structure.

💡 Hint: Consider the implications of α in terms of energy dissipation.

Question 2

A new design for a bridge must withstand strong winds. It experiences an increase in vibrations. If the damping ratio is calculated to be ζ = 1.2, evaluate the expected performance of this bridge and recommend solutions.

💡 Hint: Think of how each part of the damping works together.
