Metal stretch

[shorty]

the stretching of metal comes about when the elastic properties have been exceeded.
It doesn't take much stretch to create a big problem that requires shrinking.

Your assignment:
Acquire a strip of metal 1" wide, 12" long.
lay it on a flat surface. (table)
at one end, clamp a stop to the table.
At the other end clamp another stop to the table.
With the metal firmly situated between the stops, remove it.
Now comes the fun part.
Re-install the metal between the stops, without moving the stops,
This time with the thickness of a razorblade, (using a razorblade) between the metal
and one stop.
Note the deflection. and report back.

Shorty,

You can always shrink it back to its original shape.

Yep you can shrink it, but my point as that it takes very little stretch to create a large deformation.

Shorty,

You are right about that, I've seen a lot of people (even myself) get back into a corner with stretching metal.
