1. The lift FL on an airfoil is related to its velocity V, its length L, its chord length c, its angle of attack a, and the density r of the air. Viscous effects are assumed negligible. Relate the lift to the other variables.
2. The drag FD on an airfoil is related to its velocity V, its length L, its chord length c, its angle of attack a, and the density r and viscosity m of the air. Relate the drag to the other variables.
Design a suitable mechanism to hold the tube within its range of adjustment. Identify loads acting on the mechanism and perform necessary stress calculations to size various parts.
