Graph entitled Lift versus Airspeed. On the left side of graph is Lift designated from zero, at the bottom to 40,000 in increment of 10,000. At the bottom of the graph is Airspeed designated in increments of 50, starting at 50 and progressing to 400 to the right. A curved, diagonal line starts at zero and 50 and progresses up to the top right. The following points are plotted on the line: at an airspeed of 100 units the lift is 2,378, at an airspeed of 150 lift is at 5,351, at an airspeed of 200 lift is 9,513, at an airspeed of 250 lift is at14,860, at an airspeed of 300 lift is at 21,400, at an airspeed of 400 lift is at 38,050.
