Question 1.
What is a characteristic of static loading?
Show hintHide hint
Think about predictability over time.
Question 2.
Name an example of dynamic loading.
Show hintHide hint
Consider forces that act unexpectedly.
3Question 3.
What is the difference between static and dynamic loading?
- Static loads are time-varying
- Dynamic loads are time-invariant
- Static loads do not change rapidly
Show hintHide hint
Consider the time dependency of each type of load.
4Question 4.
True or False: Dynamic loading can cause stress spikes even under low loads.
- True
- False
Show hintHide hint
Reflect on how forces interact with structures dynamically.
Question 5.
Design a simple bridge structure accounting for both static and dynamic load factors. Discuss what parameters you would consider measuring stress distribution.
Show hintHide hint
Consider both the steady and sudden forces on your structure.
Question 6.
Analyze a scenario where a building designed only for static loads is subjected to a sudden earthquake. Predict the failure points based on stress distribution.
Show hintHide hint
Reflect on how different areas within the structure adapt to changing stress.
