Ingenius, isn't it? :cool:

Shexey... :lol:

Did you know the thread of a screw acts as an inclined plane? It delivers a mechanical advantage because you turn the screw a lot to have it go into the wood a little. Thus, the distance moved is greater than the delivered force? Clever eh!

345, used a lot in building to confirm square corners.

The scale of the drawing is pish btw, if that represents 3cm then the other side is well over 4

I think the scale of the horizontal axis is twice that of the vertical... Or we are looking at the diagram from an angle with the vertical axis furthest away? :blink:

Maybe you're both viewing it in widescreen, you need to change your monitor resolutions. :mellow:

I think my eyes are in widescreen... :blink:
