Question 1

What is the primary function of the Logarithmic Decrement Method?

  • To measure mass
  • To assess damping through amplitude decay
  • To determine stiffness

💡 Hint: Think about the decay observed in a pendulum's swing.

Question 2

True or False: The Half-Power Bandwidth Method relies on frequency response curves.

  • True
  • False

💡 Hint: Remember methods related to frequencies.

Challenge Problems

Push your limits with challenges.

Question 1

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.

Question 2

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.
