This figure shows a computer-generated illustration of a post. The top half of the post is colored purple and is labeled Loaded Region. The lower half is broken into three sections. The first section, making up the upper quarter of the post is colored red. The section below it is a small section, shows just a line colored orange and is labeled Break Region. The lower quarter of the illustration is colored a light green. A small section has been removed from just below the Break Region creating a small gap in the left-hand side of the post.
This graph shows five distinct lines. The first line is blue and is labeled C. The next line is colored pink and is labeled D. The next line is green and is labeled A. The next line is colored yellow and is labeled X. Finally, the last line is colored dark blue and is labeled B. The vertical axis of this graph ranges from zero to 30 and represents Hourglass to Internal Energy Ratio in Percentage. The horizontal axis of this graph represents Time.
The first line, the blue line labeled C begins at the point of 3 percent and spikes to 10 percent before gradually increasing to the point of 14 percent. From this point, the line oscillates as it descends and leaves the graph at 10 percent.
The second line, pink line labeled D begins at the point of zero percent and spikes to the point of 8 percent where it gradually ascends to 10 percent before oscillating off the graph at 10 percent.
The third line, the green line labeled A begins at the point of 20 percent before dropping considerably to the point of 6 percent, where it gradually ascends to 10 percent. From this point the line oscillates as it descends considerably and leaves the graph at 4 percent.
The fourth line, the yellow line labeled X begins at the point of zero percent and ascends to the point of 6 percent. From this point the line oscillates off the graph at 4 percent.
The final line, the dark blue line labeled B begins at the point of zero. From this point the dark blue line rises in a straight line to 2 percent before oscillating off the graph at the point of 2 percent.
This figure shows a computer-generated illustration of a post. The top half of the post is colored purple and is labeled Loaded Region. The lower half is broken into three sections. The first section, making up the upper quarter of the post is colored red. The section below it is a small section, shows just a line colored orange and is labeled Break Region. The lower quarter of the illustration is colored a light green. The post leans slightly to the right, however no visible damage is apparent. The post bent but not split or broken.
This graph shows five distinct lines. The first line is blue and is labeled C. The next line is colored pink and is labeled D. The next line is green and is labeled A. The next line is colored yellow and is labeled X. Finally, the last line is colored dark blue and is labeled B. The vertical axis of this graph ranges from zero to 45 and represents Hourglass to Internal Energy Ratio. The horizontal axis of this graph represents Time.
The first line, the blue line labeled C begins at the point of zero before spiking to the point of 15. The blue line then drops to the point of 10 before returning to the point of 15 where it runs straight across and off of the graph.
The second line, the pink line labeled D begins at the point of zero and ascends to the point of 5 where it then runs across and off of the graph in a straight line.
The third line, the green line labeled A begins at the point of 25 where it descends as it oscillates to the point of 5. From this point, the line straightens and runs across and off the graph at the point of 5.
The fourth line, the yellow line labeled X, and the fifth line, the line colored dark blue and labeled B both begin at the point of zero. From this point both line ascend to 5 where they runs in a straight line across and off the graph at the point of 5.
