1. Go to the Foilsim Software Program and set initial conditions as follows:
Airspeed = 100 km/h, Altitude = 5000 m, Angle = 1 deg , Thickness = 12.5, Camber = 12.5, Area = 10 sq. m.

What is the Lift? 4757 Newtons

2. Change the area as shown in the following table and record the associated lift for each area to complete the table.

3. Construct a graph of Wing Area's effect on Lift with an Independent Variable (X) of Wing Area and a Dependent Variable (Y) of Lift. Label each axis correctly to include units. Print out graph from FoilSim Program.

4. Interpolate the lift for a wing area of 70 sq. m. What is the lift? 33,299 Newtons

5. Extrapolate the lift for a wing area of 100 sq. m. What is the lift? 47,575 Newtons

6. What is the shape of the curve formed by this relationship? A line

7. Write the equation for this relationship! Y = 475.75 X where Y = lift and X = area

8. Based on the relationship between lift and area of a wing, how would you increase the lift on a wing? Increase the Area of the Wing!!!
