Best way to absorb "shocks"
« on: 18/02/2006 23:46:37 »
Hi! I was wondering....

What are the different methods or materials that help to absorb shock?

Some examples would be springs, foam, rubber...(magnets?)

So that the object getting the push, or shock, doesn't move too much. Plz help me out. ;)

Firstly, you have to discriminate between ways of reducing the peek force of an impact (i.e. the shock), and ways of reducing the energy of an impact.

A spring will reduce the peek force of an impact, but then the spring (assuming it is a perfect spring which in the real world it never is) will then rebound, and will give back that energy in the rebound.

A lump of deformable material (such as the crumple zone on a car) will not rebound, but will just absorb the energy of impact by permanent deformation.

All of the materials you include above will create an elastic collision (i.e. they will cause a rebound).  A deep pile of sand, or corrugated cardboard, or a pillow, etc., will be permanently deformed (or at least as permanently as until someone puts it back to what it was like) by the impact, but will not cause a rebound.
