Figure 12. Quasi-static (blue) and dynamic (pink) performance envelopes developed and plotted by the user. Graphs A, B, C, and D.

All four graphs show four distinct lines. The first two lines in each graph are solid blue and are labeled Static while the other two lines are pink dashed and labeled Dynamic.

1. This graph shows four distinct lines. The first two are solid blue and are labeled Static while the last two are dotted pink and are labeled Dynamic. This vertical axis of this first graph ranges from 0 to 100 and represents Force (kilonewtons) while the horizontal axis of this graph ranges from 0 to 180 and represents Deflection (millimeters). The vertical axis of this graph ranges from zero to 100 and represents Force (kilonewtons) while the horizontal axis ranges from zero to 180 and represents Deflection in millimeters. All four lines begin at the points of zero on both axes. The first blue line rises in a wide arc from the point of zero and ascends to the point of 80 on the vertical axis and 60 on the horizontal axis where it then begins to descend unevenly and gradually until it leaves the graph at the point of 30 on the vertical axis and 180 on the horizontal axis. The second blue line rises in a wide arc from the point of zero and ascends to the point of 68 on the vertical axis and 60 on the horizontal axis where it then begins to descend unevenly and gradually until it leaves the graph at the point of 20 on the vertical axis and 180 on the horizontal axis. The first pink dotted line rises from its starting point in one large arc, peaking at the point of 92 on the vertical axis and 80 on the horizontal axis before descending to the point of zero on the vertical axis and 160on the horizontal axis where it comes to an end. The first pink dotted line rises from its starting point in one large arc, peaking at the point of 70 on the vertical axis and 80 on the horizontal axis before descending to the point of zero on the vertical axis and 145on the horizontal axis where it comes to an end.

2. This graph shows four distinct lines. The first two are solid blue and are labeled Static while the last two are dotted pink and are labeled Dynamic.This vertical axis of this first graph ranges from 0 to 100 and represents Force (kilonewtons) while the horizontal axis of this graph ranges from 0 to 180 and represents Deflection (millimeters). The vertical axis of this graph ranges from zero to 100 and represents Force (kilonewtons) while the horizontal axis ranges from zero to 180 and represents Deflection in millimeters. All four lines begin at the points of zero on both axes. The first blue line rises in a small arc from the point of zero and ascends to the point of 56 on the vertical axis and 44 on the horizontal axis where it then begins to descend unevenly and gradually until it leaves the graph at the point of 10 on the vertical axis and 180 on the horizontal axis. The second blue line rises in a wide arc from the point of zero and ascends to the point of 48 on the vertical axis and 40 on the horizontal axis where it then begins to descend unevenly and gradually until it leaves the graph at the point of 6 on the vertical axis and 180 on the horizontal axis. The first pink dotted line rises from its starting point in one wide arc, peaking at the point of 54 on the vertical axis and 90 on the horizontal axis before descending to the point of zero on the vertical axis and 162on the horizontal axis where it comes to an end. The first pink dotted line rises from its starting point in one large arc, peaking at the point of 44 on the vertical axis and 80 on the horizontal axis before descending to the point of zero on the vertical axis and 140 on the horizontal axis where it comes to an end.

3. This graph shows four distinct lines. The first two are solid blue and are labeled Static while the last two are dotted pink and are labeled Dynamic. The vertical axis of this graph ranges from 0 to 10000 and represents Energy (kilonewton-millimeters) while the horizontal axis of this graph ranges from 0 to 180 and represents Deflection. All four lines begin at the points of zero on both the vertical and horizontal axis. The first blue line slopes upwards and off the graph at the points of 8200 on the vertical axis and 180 on the horizontal axis. The second blue line slopes upwards and off the graph at the points of 7500 on the vertical axis and 180 on the horizontal axis. The first pink dotted line slopes upward to the points of 8000 on the vertical axis and 160 on the horizontal axis where it comes to an end. The second dotted pink line slopes upward to the points 6400 on the vertical axis and 160 on the horizontal axis where it too comes to an end.

4. This graph shows four distinct lines. The first two are solid blue and are labeled Static while the last two are dotted pink and are labeled Dynamic. The vertical axis of this graph ranges from 0 to 10000 and represents Energy (kilonewton-millimeters) while the horizontal axis of this graph ranges from 0 to 180 and represents Deflection. All four lines begin at the points of zero on both the vertical and horizontal axis. The first blue line slopes upwards and off the graph at the points of 4400 on the vertical axis and 180 on the horizontal axis. The second blue line slopes upwards and off the graph at the points of 400 on the vertical axis and 180 on the horizontal axis. The first pink dotted line slopes upward to the points of 5000 on the vertical axis and 160 on the horizontal axis where it comes to an end. The second dotted pink line slopes upward to the points 400 on the vertical axis and 160 on the horizontal axis where it too comes to an end.
