Challenge Problems
Push your limits with advanced challenges
A wind tunnel test shows a drag force of 5 N and a lift force of 8 N on a model. Calculate the resultant force acting on the model and discuss its implications for design.
💡 Hint: Use the Pythagorean theorem to find the resultant force.
Describe how you would set up an experimental study to understand lift forces on an airplane wing in a wind tunnel. Include considerations for scaling and measurements.
💡 Hint: Think about model dimensions and flow speeds relative to real aircraft.
