The sizes of 8' x 4' for the see saw ramp is on the drawing but the hight is not. there is 2" angle 6" apart but no sizes for the hight from the floor to the top flat surface of the ramp carpet when level.
can anyone help??? and where did you see the answer.

I figure it is a little more than 13 in.

(2 X 8, 3/4 plywood, angle iron, 4 in. of rail under)

What do the rest of you think/

I also hope we get some more details.

A good question... is FIRST going to post up the AutoCAD of the blueprint? All I see is a *.pdf format of the bule print. And I believe the CAD file is going to provide a lot of details they are supposed to tell about the field.

if you do some trigonemtery, i believe at the exact midpoint of the see-saw it will be approximately 11.9" aboe the ground. Try it, im probabbly wrong. Use 92" (8') as the hypotenuse, and 24" (2') as the vertical leg of the big triangle. Using trig you get the angle of the large triangle, and the horizontal leg. Divide 92" by 2 to get the midpoint, or the vertex of your smaller triangle (this is the point directly above the ground). Using the same angle, i got 11.9" as my vertical leg. I'm probablly wrong. Oh well another wasted year of highschool math.

If the hypotenuse is 8', and the opposite side is 2', then the height at the midpoint is exaclty 1'. No trig necessary. You can just use similar trianges.

The seesaw is not 8' long, at least its not by the lousy drawing.
If you all look again its 8' 5" long. You can Hypotenuse it to death but there are no angle`s on the drawing so theres no way to tell how far off the floor it is, It definately is more than an inch and less than three feet but theres no possitive # thats real, so untill FIRST sends a size no one knows???
