This graph shows two distinct lines. The first line is colored red and is labeled Not Filtered while the second line is colored blue and is labeled Filtered at 60 HZ. The vertical axis of this graph ranges from zero to 100 and represents Force in kilonewtons while the horizontal axis of this graph ranges zero to 100 and represents Deflection in millimeters. The first line, the red line rises from the point of zero on both axes to the point of 65 on the vertical axis 60 on the horizontal axis. From this point the line oscillates heavily between the points of 65 and zero on the vertical axis until the line comes to an end at the points of 25 on the vertical axis and 95 on the horizontal axis. The second line, the blue line, ascends from the point of zero on both axes to the point of 65 on the vertical axis 60 on the horizontal axis. From this point the line descends to the point of 28 on the vertical axis and 65 on the horizontal axis where it runs in a wave across the graph until it comes to a stop at the points of 25 on the vertical axis and 95 on the horizontal axis.
