Question 1.
What is wind drag?
Show hintHide hint
Think about forces acting alongside the direction of wind.
Question 2.
What happens to the windward side of sloping roofs?
Show hintHide hint
Remember how wind affects both sides of a slope.
3Question 3.
What forces act on the windward side of a sloping roof?
- Uplift
- Suction
- Tension
Show hintHide hint
Think about how wind pushes against the structure.
4Question 4.
True or False: Wind drag acts perpendicular to wind flow.
- True
- False
Show hintHide hint
Visualize how wind moves relative to a roof's surface.
Question 5.
Design a roof structure that has to endure wind loads of varying intensities while ensuring safety. Explain how you would account for drag, uplift, and suction.
Show hintHide hint
Consider real-world examples of high-wind events and how they influence design.
Question 6.
Given a series of models with different slopes, calculate how changes in slope angles would alter uplift and suction forces in high winds.
Show hintHide hint
Test multiple angles and observe the force shifts; what patterns do you note?
