Welcome to Gaia! ::

((Well consider Kinetic Energy... ( [W*V^2/450,240] W= weight, V= velocity) lets use a smaller 28mm round operating on the squeeze bore or Gerlich principle. Already we have known data of the projectile traveling at 1400m/s or 4593 ft/s thats Mach 4.11 for those who didnt know. Thats a significant increase in speed over all equivalent sized rounds, infact thats a significant increase in velocity over rounds twice its size with three times the propellant force.

Assuming a projectile weight of 340 grams (always convert to grains when dealing with ballistic weight) is 5427 grains

So its 5427 x 4593^2= 114,486,087,123/450,240= 254,277 foot pounds of pressure. Now thats a hell of alot of force but it wont punch through that much now a days, however on rifled bullets the ratio of diameter to weight is 1::7 or for every 100% increase in diameter theres a corresponding 700% precent increase in weight. This has to do with the proper length required for a projectile to take the rifling and be spin stabalized. So assumeing that the base round (before its extruded as a smaller round) is 12.8cm or 128mm thats a 460% increase in diameter...

Which means that the multiplier of weight for the projectile is 32.2... sooo... 340 x 32.2= 10948 grams converted to grains is 168,953. Plug that into the equation assumeing the same or approximate velocity and what you get is 512,960 ft-lbs which is the equivalint of 233 tons of force focused on single point...

Theoretically assueming a mecha is 20 times larger and 200 time stronger than a normal human its still like you getting hit by a Buick... if it DIDNT penetrate it would bowl them over.. The thing is a mecha isnt a solid mechanism it has a shell that will obviously give in before the whole frame will... Aiming for things like joints just applies all that force on a weakened spot.

Of course Im not a physics major so my math and equivalance could be off but thats still a hell of alot of force...

What was I talking about again? Oh yes the OOC thread thing, just add "[OOC]" to the thread title, and I dont think there should be any problems))

OOC: Common sense puts the bridge near the center of the ship, and the "engine room" would be near the reactors which are *also* near the center of the ship. This is because there's nothing important out the fore window, and it's bad design to put the officers right in the line of fire. How often does being in the top bubble of the ship actually *help* in Star Trek?

OOC: I don't think the average mech has the firepower to take-out a single thruster anyway, let alone a small group of them.

OOC: Jay: A 20-ton mech also *weighs* 220 times more than an obese man.

((Pardon me, while I drown in a puddle of my own drool. I kid, but seriously, you lost me on the math. My character is the Engineer, not me. Anywho, speaking of Buicks, what do you think the effect of a 380mm round impact on a mecha would be? I happen to have a a few white elephants laying about which are the equal of a land battleship. I'm already certian to remove the guns and use them in a support role, but I'm rather curious.))

((A. a gundam isnt a train...
B. Calc the math yourself and compare it to just about any known metals shearability and youll find that it would take well over 1400mm equivalint of rolled homogenous steel to stop that round... thats twice the chobrams armor capacity... and atleast equivalant to gundanium, and I guaruntee gundams dont have 1400mm of armor thickness if they did it would be too heavy to move in gravity, and would exceed the bearing capacity of the ground below it. in fact i thinkt he only Mecha series that ever address the weight of fo the thing and its ability to move efficently in humanoid (non BT) way is Full Metal Panic, where they have thinsg called 'lamda drives' which somehow act against gravity, otherwise as stated some of the mecha in the series would just fall into a heap. But I suppose trying to apply physics to the gundam series that states that beyond walking, flying, and jumping easily can also apparently achieve escape velocity, is a moot point.

Josef: I dunno... what barrel length, but Id guess it would hurt like hell in all fairness. Anythign still moveing after a hit from a cannon beyond 300mm is something that is assuredly capital class, and not to be screwed with.))

OOC: Just what *everybody* needs: Intangible armor!

((*shudders considering rifts style phase weapons rearing their ugly munchitizing head into online RP*))

(a special futuristic chemical tahst mixed into the armor of mobile suits and requires a special ropogram to activate it, as well it drains the mechs energy very fastbut makes it imune to all physical and explosive weaponry. only beamd and high pwoer laser weaponry can damage the suit while the phase shift armor is active. but as i said it requires alot of energy to keep running.

as since you said your modern tech this is behold modern tech. so please don't try to make a tank with this. plus belive it or not as ive watched the series enough heavy fire power focused on the mech will cause the phase shift to suck power fast thus draining the core fast leaveing only the pwoer to move move the suit and fight ahnd to ahnd or with hard shell weapons.

rift style phase weapons?)

sounds somewhat like a variable speed beam rifle or cannon. except thoes use special particle blasts that can be adjusted in speed to penetrate energy fields or pierc heavy armor and they over heat after just a few shots.
