like whot bout be the surfice area of a mech??

lets say

Mad Cat
Atlas
Zaku 2(just for fun)
AT-ST
something thats 20 ft high(gernirc mech)

any others you might want to add

For a really quick calc, let's say it's 6 m by 3 m, with 3 m legs, each 1 m wide. That's a frontal SA of 15m^2. A square metre of steel weighs nothing, but let's say you want it to be 30cm thick, that's a total of 4.5m^3, at a density of around about 8g/cm^3 I make that 36 tons. You need some on the top, sides and back (let's say the body is 2m front to back and the legs 1m), let's go for 10cm armour off the front, that comes to the same again (not a coincidence, I'm lazy).

Whoa, 72 tons of armour is a hell of a lot. Let's halve it all-round, down to 36, somwhat more reasonable. That's 15 cm on the front, 5 cm elsewhere. Not a massive amount. While modern tanks don't use steel, AFAICT the Tiger II had armour around 4cm \ 8cm \ 10cm \ 15cm (roof \ sides & rear \ hull front \ turret front, although the slope would have helped significantly. It weighed around 70 tons total, but had a total volume around about three times that of this mech. I can't be bothered to play around with the numbers any more, but feel free.

what i ment about a squair meter was a block 1 meter in size and 15cm is 6 inches that good enought to defend it(unless you got realy good Shaped charges or APDS rounds(wich the norm):(

1 cm of steal is 8g?

Actually modern tanks do use steel armor, composite is a major part but RHA steel makes up much of the protection. Generally you find composite on the frontal arc, with some on the sides. The composite is normally inside of two peices of RHA.

Sea Skimmer: Uh yeah. Oops

1 cubic centimetre is about 8 grams (I found that figure for stainless steel, and I don't think it varies too much)

15cm isn't that much against modern anti-tank weapons, given that they can penetrate the best part of a metre of steel. IIRC the 40mm cannon on a CV90 can penetrate the side or rear armour of any tank with the right ammo, and the A-10 can famously frag most through the top armour with a 30mm. Here's a site which estimates the equivalent thickness of RL tank armour. Obviously the modern stuff is gonna be rough because it's kinda classified, but the older stuff should be fairly close. Doesn't give any for the sides\rear\tops, and it's hard to find similar data for lighter vehicles, but I think 15cm is better than most IFVs and light tanks. Whether that weight of armour is practical is another matter, it's the volume limitation in particular.

Either English is not your native language or you're retarded. Please clarify.

So that's 2 Battletech, 1 Zeon and 1 SW...i don't know about the rest but the Zaku 2 is roughly 18 m tall...

I refuse to consider questions from those who can't figure out the mass density of steel or spell "square".

Then you're an idiot.

Look, I can't spell very well, but I actually took the fucking time to LEARN how to spell.

I'm thinking the real reason is that you're just fucking lazy, or that you're in one of the worst school districts in Ohio.

Oh, and use some fucking punctuation and capitalisation, baka.

I believe the Atlas is on the stubby side...12m tall or so.
Going roughly by my miniature of it, it's about 3m wide (at the hips), legs up to half that. Each leg about 1m wide, maybe double that deep, 6m high. Cockpit maybe 1m tall, soooo....
48m^2 for the legs
arms approximately the same size as the legs, a little thinner, but when you're measureing tool is a dollar bill and the mark 1 eyeball, it's good enough.
torso would be 36m^2 (total) for front and back, 24m^2 to the sides.
All together, that comes to 156m^2 for the surface area.

I think this is what Shortie calculated...tank 12mx3mx2m has more internal volume than Atlas (space between the legs, arms, body, etc.), 132 m^2 surface area--doesn't seem like a big advantage, ~1/8 the surface area (before turret is added, although IIRC, a T-90 is 2m high inc. turret.), but much less needs the heavy frontal armor.

I thinks spankey shoud be band from the forms!!

Its not that i cant spell its because i have a milled form of autisem!!!

I should be banned for not knowing you're autistic, despite you never mentioning it?

LOL

How old are you, anyway? Your knee-jerk reaction is extremely immature.

Feel free to fuck off. [1] Any halfway decent PC will have some form of spell checker in its word processor. [2] You're not the only person who has autism here. [3] We really don't give a fuck anyway, the only other person who attempted to use autism for as an excuse for being a idiot ended up banned.

You're still a fuck-wit. It's just you're now trying to pass it off as a disability.

We don't care. If you feel like being an ass, feel free to leave this board.

I can't spell either, and sometimes my capitalization gets a little FUBAR. aside from that, I generally I do appreciate punctuation and spacing, and I tend to make far more intellegent posts then this steaming pile.

BTW how is your little friend and did you read my post involving the Boneless Chicken rescipie?

Well, to be fair, it's not like I expect anything more from an American...

I so hope Rob or Damien don't see this, by the way.

Besides the fact that alot more than just those two are American.

Then again, this clod does kinda sum up the anti-intellectualism of American society quite well, whether or not he is actually clinically mentally handicapped.
