I have steel ramps, but they are very short and suitable for my [low] trailer only.
I am considering making ramps from wooden boards. Specifically, picture a ramp that looks like a letter I in cross section. The wide part of the I is a 2x8. On the top and bottom of the I, there would be
2x4s. The "I", of course, would be laid flat for use.Here's the ascii graphic:

The 2x4s would be screwed to the 2x8 with wood screws, and reinforced with glue.
My question is, what would be the strength of this ramp if it was, say, 8 ft long. Specifically, how much load could I place in the middle for some reasonably low deflection (like 1-2 inches).
thanks
