Question 663042
the height of the leg opposite (h) the slope angle can be determined by the tangent of the slope angle
:
A 30 degree slope
tan(30) = {{{h/66}}}
h = 66 * 38.1 inches high
:
An equation for the height for various angles would be
h = 66 * tan(slope angle)
:
Most calc have the tangent function, just select that function enter the
slope angle, multiply that value times 66 and you have the height
:
For example for a 35 degree angle
h = 66 * tan(35)
Find the tangent on the calc
h = 66 * .70
h = 46.2 inches
:
If you have to fabricate this from say 5" thick sheets of foam
get rectangles of 66 by 40, assemble enough layers to get the max height
that you need. (46" would require about 9 layers)
cut the rectangular cube opposite corners, if the height is right the angle
will be right.
Since you now have two of these triangular solids, you can cut one down
to have less of slope, hence less height.
:
I know foam is pretty expensive, my wife sews stuff, and buys it a a place called Hancocks where they have many different sizes, so perhaps you could have
a triangle form built of wood and glue a 5" layer on it.  If could be made to
have an adjustable height. hope this helps. C
