Challenge Problems
Push your limits with advanced challenges
Describe how you would evaluate the damping ratio of a structure using both the Logarithmic Decrement and Half-Power Bandwidth methods. Include the steps involved in each method.
💡 Hint: Think step-by-step through data collection and calculation.
Imagine you have two different materials for a structural component: one is very resilient but has a low damping ratio, while the other is weaker but has a high damping ratio. Discuss the trade-offs and implications for engineering design.
💡 Hint: Consider seismic forces versus material strength.
