4.2.1. Definition

Try these first

1. 1.

   Define dynamic excitation in your own words.

   Hint

   Think about how forces change in nature.

2. 2.

   List two examples of dynamic excitation.

   Hint

   Consider events that cause movement.

3. 3.

   What characterizes dynamic excitation?

   • Constant forces
   • Time-varying forces
   • Static loads

   Hint

   Consider the definition of dynamic.

4. 4.

   True or False: Inertia effects are negligible in dynamic excitation.

   • True
   • False

   Hint

   Think about how movement is influenced by mass.

5. 5.

   A suspended bridge is experiencing dynamic excitation from wind gusts. How would you approach determining its response to varying forces?

   Hint

   Think of all methods engineers use to model changing forces.

6. 6.

   Design a simple structure that can handle dynamic loads and explain how different materials might affect its resilience.

   Hint

   Consider the properties of materials and how they interact with forces.
