1. Force-deflection. This graph shows four distinct lines. The first line is solid red and is labeled DS-65 Southern Yellow Pine. The second is dotted yellow and is labeled Grade 1 Southern Yellow Pine while the third line is solid blue and is labeled Grade 1 Douglas fir. Finally, the fourth line is solid green and is labeled Grade 1 frozen S. Yellow Pine. The vertical axis of this graph ranges from –50 to 100 and represents Force (kilonewtons) while the horizontal axis of this graph ranges from 0 to 600 and represents Deflection (millimeters). All four lines begin at the points of zero on both the vertical and horizontal axes and run across the length of the graph in waves. The red line first peaks at the points of 90 on the vertical axis and 80 on the horizontal axis. It then slopes down to the points of –40 on the vertical axis and 190 on the horizontal axis where it slopes back up to the points of 30 on the vertical axis and 270 on the horizontal axis. The red line then sloes down again to the points of –15 on the vertical axis and 370 on the horizontal where it then slopes up one last time to the points of 15 on the vertical axis 470 on the horizontal axis. The red line completes its wave-like format, sloping down to its end at the points of -5 on the vertical axis and 550 on the horizontal axis. The remaining three lines follow the same pattern as the red, only in much smaller waves. The yellow line first peaks at the points of 50 on the vertical axis and 70 on the horizontal axis where it slopes down to the points of –20 on the vertical axis and190 on the horizontal axis. From there the yellow line slopes back up to the points of 15 on the vertical axis and 290 on the horizontal axis where it slopes down to the points of –5 on the vertical axis 360 on the horizontal axis. It then slopes back up gradually to the points of 5 on the vertical axis and 450 on the horizontal axis where it slopes back down to its end at the points of zero on the vertical axis and 600 on the horizontal axis. The blue line first peaks at the points of 45 on the vertical axis and 65 on the horizontal axis where it slopes down to the points of –15 on the vertical axis and 190 on the horizontal axis. From there the blue line slopes back up to the points of 15 on the vertical axis and 250 on the horizontal axis where it slopes down to the points of –5 on the vertical axis 340 on the horizontal axis. It then slopes back up gradually to the points of 5 on the vertical axis and 450 on the horizontal axis where it slopes back down to its end at the points of zero on the vertical axis and 600 on the horizontal axis. The green line first peaks at the points of 30 on the vertical axis and 65 on the horizontal axis where it slopes down to the points of –20 on the vertical axis and 190 on the horizontal axis. From there the green line slopes back up to the points of 10 on the vertical axis and 250 on the horizontal axis where it slopes down to the points of –5 on the vertical axis 340 on the horizontal axis. It then slopes back up gradually to the points of 5 on the vertical axis and 450 on the horizontal axis where it slopes back down to its end at the points of zero on the vertical axis and 600 on the horizontal axis.

2. Velocity-time. This graph shows four distinct lines. The first line is solid red and is labeled DS-65 Southern Yellow Pine. The second is dotted yellow and is labeled Grade 1 Southern Yellow Pine while the third line is solid blue and is labeled Grade 1 Douglas fir. Finally, the fourth line is solid green and is labeled Grade 1 frozen S. Yellow Pine. The vertical axis of this graph ranges from 0.0 to 1.0 and represents Velocity (meters per second) while the horizontal axis of this graph ranges from 0.00 to 0.07 and represents Time (s). All four lines begin at the points of zero on both the vertical and horizontal axes and run across the length of the graph in waves. The red line first peaks at the points of 0.95 on the vertical axis and 0.015 on the horizontal axis. It then slopes down to the points of 0.65 on the vertical axis and 0.025 on the horizontal axis where it slopes back up to the points of 0.85 on the vertical axis and 0.035 on the horizontal axis. The red line then sloes down again to the points of 0.75 on the vertical axis and 0.045 on the horizontal where it then slopes up one last time to the points of 0.9 on the vertical axis 0.06 to its end. The remaining three lines follow the same pattern as the red, only in much smaller waves. The yellow line first peaks at the points of 0.45 on the vertical axis and 0.015 on the horizontal axis where it slopes down to the points of 0.35 on the vertical axis and 0.025 on the horizontal axis. From there the yellow line slopes back up to the points of 0.45 on the vertical axis and 0.035 on the horizontal axis where it slopes down to the points of 0.4 on the vertical axis 0.04 on the horizontal axis. It then slopes back up gradually to the points of 0.45 on the vertical axis and 0.05 on the horizontal axis to its end. The blue line first peaks at the points of 0.43 on the vertical axis and 0.015 on the horizontal axis where it slopes down to the points of 0.35 on the vertical axis and 0.025 on the horizontal axis. From there the blue line slopes back up to the points of 0.5 on the vertical axis and 0.035 on the horizontal axis where it slopes down to the points of 0.45 on the vertical axis and 0.04 on the horizontal axis. It then slopes back up gradually to the points of 0.5 on the vertical axis and 0.05 on the horizontal axis to its end. The green line first peaks at the points of 0.3 on the vertical axis and 0.015 on the horizontal axis where it slopes down to the points of 0.2 on the vertical axis and 0.025 on the horizontal axis. From there the green line slopes back up to the points of 0.25 on the vertical axis and 0.032 on the horizontal axis where it slopes down to the points of 0.2 on the vertical axis 0.04 on the horizontal axis. It then slopes back up gradually to the points of 0.25 on the vertical axis and 0.05 on the horizontal axis to its end.

3. Displacement-time. This graph shows four distinct lines. The first line is solid red and is labeled DS-65 Southern Yellow Pine. The second is dotted yellow and is labeled Grade 1 Southern Yellow Pine while the third line is solid blue and is labeled Grade 1 Douglas fir. Finally, the fourth line is solid green and is labeled Grade 1 frozen S. Yellow Pine. The vertical axis of this graph ranges from 0 to 700 and represents Displacement (millimeters) while the horizontal axis of this graph ranges from 0.00 to 0.07 and represents Time (s). All four lines run diagonally across the graph in a straight-line beginning at the points of zero on both the vertical and horizontal axes. The red line finds its end at the points of 550 on the vertical axis and 0.062 on the horizontal axis. The yellow line finds its end at the points of 620 on the vertical axis and 0.062 on the horizontal axis. The green line mimics the yellow line completely. The blue line finds its end at the points of 580 on the vertical axis and 0.062 on the horizontal axis.
