cantilever vs leverage system?

this was brought up in another post, but I didn't want to jack the guys post.can someone explain the major differences of a true cantilever vs. a true leverage systemhttp://streetsourcemag.com/Forum/topic.aspx?method=reply&topic_id=94712&forum_id=16&forum_title=&M=True&S=Trueit seems that this is a very common misconception..every cantilever post has pics of leverage systems..can someone clarify this?

are'nt these more of a leverage setup?

having trouble posting these..sorry

actually couldn't the blue framed one be a true cantilever?

To me a leverage advantage is a bags on bars setup. Setups like the one on the green frame where the bags push on a pivot system to lift the vehicle are a cantilever system to me. That is just my opinion though. Max will be much more knowledgeable on this.

Actually this one is really hard to come up with a solid answer. By definition, the typical "leveraged" 4-link that we see most often (bags on bars) is a cantilever. The blue truck above is a good example of a "bell-crank" used to "leverage" the bag (or shock) a desired amount. The other two pics are better described as "rocker arms."

So how do you categorize the different type of systems?

-A traditional link design using the lower bars as cantilevers.

and

-A traditional link design using a rocker-link as a mechanical advantage over the bags.

???

I have done a bit of homework on this subject and have not found a difinitive answer, so I am sorry, I can't clear this up...

max i as well have not found a definitive answer even in the industrial design sense. ive heard it being argued as the same thing but a leverage system doesnt always with hold the cantilever concepts that which makes the potruding cantilever arm making the top part of the vertical side in tension and the bottom in compresseion...thanks for ur comments max

In industrial design, a cantelevered beam is one that is ridigly mounted at one end, and supports a load either at the end, or along its length. So to classify any suspension with pivoted ends as a cantilever would be incorrect.
