Wedge

Having the stairs as wedges increases strength greatly.

Blueprints

This is a print out of the illustrator file that I will get laser cut. The staggered steps are precisely placed and even the thickness of the material that it will be cut from has been taken into account to ensure a perfect allignment.

The sketch on the far right shows a way that the steps could fold out, instead of being completely flat, they could have a flat surface and an angled surface. This will make the whole step much stronger. The step and underside of the step will be different lengths. If I know how long the flat surface and the gap from where the flat surface joins the wall and where the angled surface joins the wall, I will be able to work out how long the angled surface is, as it is the hypotenuse.

Length of hypotenuse c = √(a² + b²)

Hinges?

I need to think of a better hinge solution than tape....
