Challenge Problems
Push your limits with advanced challenges
Consider a scale model bridge over a river. If the bridge model scales down to 1/200 while keeping the same fluid characteristics, derive the force resisting the bridge based on fluid interaction.
💡 Hint: What scaling principles would you apply, and how do they relate to the bridge's real characteristics?
If a water model at a 1/1000 scale shows resistance of 0.05 N under specific conditions of flow, what would be the expected force under prototype conditions?
💡 Hint: How does the dimension scale affect force predictions?
