Something elastic.
Elastic can be stretched and then reverts back to its original shape.
a rectangle streched out from the back and front......I'm gonna guess
Of course, it will not crack easily. After you pushed it up it, it will just go back to its normal shape.
That would be a spring, which is stretched when you apply force to it. The spring used have a specific force constant, which means that an extension of the spring to a certain length is equal to a fixed amount of force.
It can revert back to its original shape.
WaTer
They are called smart shaped memory alloys they go back to their original shape when heated
a horseshoe
You can't.
Elastic or Rubber
No. Well you could bend tham back into shape but the chances of the engine even running at all are low as you would have to get them back to their perfect original shape. They'd rip the guides to shreds if they are slighly out of shape, and before long, the cylinder head.
That's impossible. It would be in the exact same location as before.
