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.
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.
