Obsidian = Onyx?

[zach312]

If the Cape is made of stone, wouldnt it be much heavier then 2kg?

 

 

 

 

 

 

 

Actually, it probably wouldn't. Obsidian is a ridiculously light rock, and is, as others stated, more like glass than anything. Hard but not as hard as most other rocks.

what are you talking about soma maybe you from another country i don't know really but in america pounds is a measurement of weight or mass not force...

 

 

 

clearly, soma has taken a physics course. clearly, you haven't. he was correct; the pound is a measurement of force, which is basically the same thing as its weight.

 

 

 

 

 

 

 

yes, kilograms are a mass, but you don't hear someone asking how many kilogram-accelerations you weigh, do you? because the acceleration due to gravity is practically constant at the surface of the earth, you'd just be multiplying everything by 9.8. which makes using just kilograms to describe your weight, when considered relative to others, valid.

 

 

 

 

 

 

 

ANYWAYS, what was the topic about? oh right, factual accuracy. surprising that i ended up actually being on topic :thumbsup:

 

 

 

 

 

 

 

either way, soma's comment was unnecessary and arrogant. No one cares, i think most people would assume that we are on earth. if you dont, then computers aren't allowed in area 51

 

 

 

 

 

 

 

 

 

 

 

as for the topic at hand, everone is wrong. this is no earth obsidian, this is obsidian made from four-armed, naked lava people, which obviously means its very, very strong

[atestarossa]

I've seen a rock of obsidian IRL, or "volcanic glass" as it's usually called. And for onyx, it's a real gem, I actually got a few of them.

 

 

 

 

 

 

 

 

 

 

 

WOW you must really be rich irl!!!!!!!!!!!!!!!

 

 

 

 

 

 

 

ps: just kidding

 

 

 

 

 

 

 

 

 

 

 

on topic again: it is true as it is said, obsidian is "naturly made volcanic glass" and onyx exsist too :P

[drgnslyer_15]

 

 

well, 2kg is around 6 pounds+, and if you examine it, it is interwoven plates, not just solid obsidian.

 

 

 

 

 

 

 

my guess is these plates are less than a 1/4 an inch thick, maybe less. i do not think that that would weigh more than 6 or 8 pounds on your back.

 

 

 

 

 

 

 

2kg is 4.4 lb

 

 

 

 

 

 

 

That is false.

 

 

 

 

 

 

 

2kg IS NOT 4.4 lb. Pounds is a measurement of FORCE in the english system, while Kilograms is a measurement of MASS.

 

 

 

 

 

 

 

2 Kilograms EXERTS approximately 4.4 pounds of force at earthnorm gravity. However, 2 Kilograms is NOT 4.4 pounds.

Well for us in The United Stats we are taught 1 kg = 2.2lbs other than that we don't go into detail the metric system simply cause its not that important to us.... Or at least my school doesn't think so ....

Before anyone says "In the USA were taught 2.2 pounds = 1 kilogram", I was born in America and always attended public schools in America. And that is where we learned that kilograms are mass, and pounds are weight/force.

 

 

 

 

 

 

 

If I had said 10 miles is equal to 20 minutes, someone definitely would have corrected me as well, because I am taking it out of context. Yes, a car will go approximately 10 miles in 20 minutes if it's driving at an average velocity of 30 miles per hour, but that doesn't make 10 miles equal to 20 minutes.

 

 

 

 

 

 

 

It's a similar situation with pounds and kilograms. They are completely different units of measurement, but can be derived from each other from certain formulas. If I had gone around posting that 10 miles is 20 minutes , someone would certainly correct me as well.

 

 

 

 

 

 

 

This is not "arrogance". It's just another attempt to stop further spreading of a common misconception.

 

 

 

 

 

 

 

And back on topic, a cape made out of obsidian plates would definitely weight more than 19.6 N on earth. But there also aren't boots that reduce your mass. Magic applies to both I suppose.

Soma, if you don't believe us, look it up on Wikipedia or google it.

 

 

 

Pounds can be a unit of mass, and force...

 

 

 

The official name for the pound when measuring mass is the international avoirdupois pound though that name is never used. When measuring force on the other hand, it should be called a pound force.

 

 

 

 

 

 

 

-or-

 

 

 

 

 

 

 

MYTH: Pounds are units of force, and not units of mass.

 

 

 

 

 

 

 

I've run into this statement several times in various newsgroup threads. It seems to pop up at least once a month on one newsgroup or another. On one newsgroup, after I had pointed out that as a farmer I know that as they are used today, bushels are usually units of mass (differing amounts for different commodities) rather than units of volume, someone responded:

 

 

 

 

 

 

 

And as an engineer, I feel impelled to point out that the pound is a unit of weight, not mass. :)

 

 

 

 

 

 

 

The pound mass is the older definition of the pound. It is also the primary definition of the pound.

 

 

 

 

 

 

 

Back in 1893, the United States abandoned its independent standards for pounds and yards and defined them as fractions of the kilogram and the meter.

 

 

 

 

 

 

 

In 1959, the directors of the national standards laboratories of the United States, Canada, the United Kingdom, Australia, New Zealand, and the Union of South Africa got together to agree on common definitions of the customary length and mass units. They defined the pound avoirdupois as 0.453 592 37 kg, and the yard as 0.914 4 m, exactly. These metrologists were quite aware of the difference between force and mass, and they defined the pound as a unit of mass.

 

 

 

 

 

 

 

Before the redefinition of the pounds as fractions of a kilogram, they were defined as the mass of independently maintained artifacts.

 

 

 

 

 

 

 

The modern practice is to use pounds and ounces, etc., for the mass units with the symbols lb, oz, etc. If the force units of the same name are used, they should be identified as such (pounds force, ounces force, short tons force, long tons force). The symbol for the pound force is lbf, and the symbol for the ounce force is ozf. The old engineering practice of using lbm for pounds mass is obsolete. See, for example, the list of units and conversion factors in NIST Special Publication 811.

The international avoirdupois pound isn't really used. The proper measurement of mass in the English system is the Slug I believe. 0.031... slugs exerts 1 pound of force.

 

 

 

 

 

 

 

And actually, noone said "it can be a unit of mass and force". Yes, there is technical method of using pounds as mass but I don't believe that's the one they're using.

That may be the modern practice but scientifically, it's still wrong. It's more convenient but still false.

ya onyx is a real stone

 

 

 

i have alota rings with onyx in them

 

 

 

i like onyx :D

 

 

 

they r cool

That I can agree with. Onyx are really nice looking stones IMO.

speaking of onyx rings :D

 

 

 

im gonna wear mine today when i go in 20 min

 

 

 

its pretty awsome

 

 

 

one big onyx in the middle with dimond studs

[SanFranciscoGiants]

 

 

 

 

 

 

 

Obsidian is a dark stone which can be used in jewlery. The Aztecs shapred obsidian and used it in their weapons.

 

 

 

 

 

 

 

I'm maknig this connection the the Onyx stone in rs and to the Obsidian cape

 

 

 

 

 

 

 

If the Cape is made of stone, wouldnt it be much heavier then 2kg?

 

 

 

 

 

 

 

Cool thought...the cape should weigh more unless its made up of very tiny pieces

[Atroxide]

 

 

 

 

If the Cape is made of stone, wouldnt it be much heavier then 2kg?

 

 

 

And how does a cannon fit in your backpack? Don't mix up RS and real life =P~

 

 

 

Also dont forget you dont have a backpack =P~

[aj926]

 

 

And you expect things in a game like Runescape to resemble real life because?

 

 

 

 

 

 

 

Next you will be complaining about the dragons cause they aren't real. :roll:

 

 

 

 

 

 

 

Agreed... Or how teleporting isn't actually in real life...

 

 

 

 

 

 

 

This topic isn't really necessary

 

 

 

 

 

 

 

And while we're feeling existential, was you posting neccissary?

 

 

 

 

 

 

 

I find this much more interesting than weddings, tyvm.

 

 

 

 

 

 

 

I don't think this relates to cannons, because a set up cannon really is more fantasy, discussing why the wieght of an item is as heavy as it is isn't. This being said, I continue.

 

 

 

 

 

 

 

I can see what he's saying. OK, I passed science, I know that they are two different things, but look at it from the average RSer's POV. There are two items derived from the same place, they are both the same color, and they both give better + stats than the previous best items of their class. They are and should be linked for the brief moment in time when worn in conjunction they were the best items in their class.

 

 

 

 

 

 

 

Being linked, I could see how you could be confused.

 

 

 

 

 

 

 

 

 

 

 

Good post.

 

 

 

 

 

 

 

 

 

 

 

On the subject of the cape, I agree with the poster that said they were glass tiles and would wiegh about the same. I won't get into the wieght/mass controversy, I don't want to get flamed enough that my foot falls off.

well, 2kg is around 6 pounds+, and if you examine it, it is interwoven plates, not just solid obsidian.

 

 

 

 

 

 

 

my guess is these plates are less than a 1/4 an inch thick, maybe less. i do not think that that would weigh more than 6 or 8 pounds on your back.
