The pic speaks for itself I think:

The answer is 11,because the Common Core System now being taught in the schools allows that 3x4='s 11 as long as the student can show how they arrived at that answer and that they feeeeeeeeeeeeeeeeeeel good about themselves.

are you asking if the center to center distance on the 'blue' holes will be longer as part 2 is lifted up?
I believe you could say no, as the formula Sq.Rt of a2 + b2 = that diagonal distance measured at approx 45 degrees from the pivot point does not apply if I'm thinking of this correctly as the other hole would always move in the direction closer to the other blue hole. Of course I'm assuming the blue holes are on the same centerline as the hinge pivot hole.

I don't have the math to figure out how far, but until somebody with it steps in I am going with my first guess (that is all it is) and say yes.

Yes, that's it exactly.

The centerlines of the hinge and the blue holes are about 1/4" different, the blue holes being 1/4" lower than the hinge centerline.

That was my best guess too. I figured they would get slightly farther apart within the first few inches of lift of part 2. I just can't prove it to myself. And then cdennyb comes up with a common sense and logic approach and makes me further doubt my guess!

Dang. Now its going to bug me.
If nothing else I suppose we could make a small flat paper scale model that can be laid on a piece of paper that has a circle drawn using the center of X as its start.
We could than visually see it when it changes length.

And at the end of the day everybody gets an award just for showing up.

Gonna say no. No math being used to back up my answer, but keeping x (A) a straight line measurement, the radius and offsets don't appear to do anything to increase the distance.

Cheers,

Give everyone a trophy and a slurpie for reading this and replying.
My answer ....no, when folded in half it can never be longer than the original length. At least from my 5am interpretation.

No, it will never get longer. I'd attempt to prove it but it sounds like you'll find out soon!..lol
