2.3. Wind Drag

Try these first

1. 1.

   What is wind drag?

   Hint

   Think about forces acting alongside the direction of wind.

2. 2.

   What happens to the windward side of sloping roofs?

   Hint

   Remember how wind affects both sides of a slope.

3. 3.

   What forces act on the windward side of a sloping roof?

   • Uplift
   • Suction
   • Tension

   Hint

   Think about how wind pushes against the structure.

4. 4.

   True or False: Wind drag acts perpendicular to wind flow.

   • True
   • False

   Hint

   Visualize how wind moves relative to a roof's surface.

5. 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.

   Hint

   Consider real-world examples of high-wind events and how they influence design.

6. 6.

   Given a series of models with different slopes, calculate how changes in slope angles would alter uplift and suction forces in high winds.

   Hint

   Test multiple angles and observe the force shifts; what patterns do you note?
