1. What is the value of lift for the original parameters?
0 pounds
2. Determine the Lift value for each of the prescribed Angle
levels, while keeping the other values the same.

3. On the graph below, graph the values for Angle and
Lift. (Place the Angle on the y-axis and the
Lift On the x-axis.)
.
4. What is the relationship between angle
and lift? By doubling the
angle, you double the lift. It is a linear
relationship
5. Write an equation that will sum up this
relationship. Lift = Angle x
constant
6. Using FoilSim, and keeping the angle set at 4 degrees,
determine the Lift values for the following Airspeeds.

7. On the graph below, graph the values for
Airspeed and the corresponding Lift levels.
8. What is the relationship between the
airspeed and lift? By doubling the
airspeed, you quadruple the lift.
9. Write an equation that will sum up this
relationship. Lift = Airspeed
squared x constant
