This graph shows two distinct lines. The first is a solid green line with green dots and is labeled G subscript F perp equals 50 G subscript F para while the second is solid red and is labeled G subscript F perp equals 250 G subscript F para. The vertical axis of this graph ranges from 0 to 60 and represents Force (kilonewtons) while the horizontal axis of this graph ranges from 0 to 200 and represents Deflection (millimeters). Both lines start at the points of zero on the vertical and horizontal axes. The green line mirrors the red line as they both spike upward. The green line falls away from the red as it peaks at the points of 45 on the vertical axis and 30 on the horizontal axis, where it drops straight down to the points of 13 on the vertical axis and 13 on the horizontal axis. From there the green line spikes again in the slightest to the points of 19 on the vertical axis and 45 on the horizontal axis where it slopes downward in the least to its end at the points of 15 on the vertical axis and 115 on the horizontal axis. The red line continues its arch up and over the first green line peak where it peaks, itself, at the points of 49 on the vertical axis and 50 on the horizontal axis. From there the red line makes a sporadic drop, and plateaus at the points of 13 on the vertical axis and 105 on the horizontal axis for some time before dropping off again where it leaves the graph at the points of 5 on the vertical axis and 200 on the horizontal axis.
