One sinks, the other doesn't. ;)

Armor that 'floats' isn't solidly located on your person, and will shift around as you move. Armor that does't 'float' is strapped, pointed (tied with laces to other armor, or the clothing you are wearing), or otherwise attached to you more snuggly than floating armor.

Hi,

Tassets are a good example.

When someone hits my tassets, they are "floating" out from my body.

In turn those tassets must move maybe an inch or so, bleeding off the power of the shot. Then they hit my leg, with that greatly reduced power spread out over the tasset.

A inch and a quarter by maybe two inch (2.5 inches square) impact is now trying to move a plate that is 10 inches by 8 inches (80 inches square). And have a noticeable impact upon my 16 gauge stainless leg armour.

If we assume that the speed to the blow is equivalent to a 100 mph fastball from a professional pitcher, the acceleration would be about 1760 inches per second squared, and the mass is 5 pounds with a surface area of 2.5 inches with a force of 8800 pounds x inches per second squared (3520 pounds over those 2.5 inches).

A considerable force indeed.

But when it impacts the tasset, the force is spread out over 80 inches squared, reducing the 3520 pounds of force into 110 pounds inches of force.

Then that tasset must move into my 16 gauge stainless leg.

If the tasset is out from my body by say 3 inches, then that acceleration is cut by about a third by the time it reaches my thigh. We've gone from 1760 inches per second squared to 586.7 inches per second squared.

The tasset took a grand total of 0.04 seconds to move, but the power loss is considerable.

In turn that 586.7 inches per second squared of 2 pound tasset produces 1173 pounds inches, which hits my stainless leg (weight of 5 pounds) and thigh (weight of also five pounds) with a surface area of 75 inches squared.

This produces an impact of 1.56 pounds per inch. That's barely a kiss.

A super-duke shot has become a butterfly kiss.

And that's why I have to ask my opponent to let me know if they got a leg shot. It's almost theoretically impossible to feel that shot.

Oddly enough, armour works sometimes.

And that's the reason my 18 gauge stainless legs (built to a cast to be skin tight) from Ken are coming. I hope to feel shots through them.

I'll end up getting spanked for my math...it's rusty by 20 years. But basically the "floating" armour needs to travel before the impact is felt, and this bleeds off a considerable amount of power. Or in the example of a Coat of Plates where the plates lay upon each other, the power may actually never reach it's destination.

When you have "floating" armour you must inform your opponent so they can gauge the blows to those section for you...because you can't feel something that light. :(
With respect,

Hi,

The basic concept is that "floating" armour is armour that isn't on the skin.

Interesting. I always interpret this as a distinction between articulated and non-articulated. A single elbow cop that points to the elbow and is not attached to rerebrace or vambrace is a "floating" cop.

I guess the terminology isn't exactly defined yet.

And, mm - just how is "floating" armor kept on, in your definition, Alcyoneus ? And no, I'm not being smug, I'm looking for some clarification of language that is confusing to me.

One of the best examples I can think of would be an export half-harness...

Rerebrace, floating elbow, and three-quarter vambrace.

That's pretty much the way I meant it, Kilkenny, not so much a tasset that might bridge between armor.

I used to have 'floating knees'. A strap or two went up to my kidney belt, but nothing really kept the knees from floating this way, or that way. They were way to big, poorly shaped, and badly strapped.

I wore them for years. :oops:
