Los Angeles physicist, checking in

Hello All! Joining the forum! I'm the proud owner of a 2001 Honda Rebel. I've used it as my primary transportation for about 8 years now, and I've survived over 30k miles as a daily commuter in LA traffic.

I will be trading up to a 2012 BMW F 800 GS within a couple of weeks (already got the deposit down! ) Don't worry about the rebel - my wife just got her class M, too.

And yes, I am a rocket scientist.

Welcome to the board. Post up some pics of the Rebel. We all like bike pics. What exactly do you do as a physicist? Sounds very interesting. Maybe you can consult on any new novels I'm working on.

In any case, welcome.

Welcome to WT, the best rider's forum on the web! Well, since I joined it that is.

Maybe you could give me a hand with a compact fusion reactor that needs some mathematical lapel pressing. What's life without a challenge?

Rob

If it has already been done, it is safe to assume it is possible to do it.
On the other hand, if it has not been done never assume it is impossible to do it.

Yo Rocket Scientist! I've known a Scoby up here in Santa Barbara for quite some time. He's no rocket scientist, just one hell of a wild and crazy guy.

Well, I have a rocket, and once in a while (not as often as PVster) it goes boom.

A rocket has (of course) a rocket engine, but is not actively guided. A missile has a rocket engine and an active guidance system.

I have a question. An object floats based on how much water it displaces. It displaces water untill it has displaced enough water to equal it's weight.Right.? Okay we'll if you fill a tire with air it will float but after about 40 psi the tire doesn't change shape anymore so my question is will a tire that is at 40 psi have more floatation than a tire that is at 100 psi because in order to reach 100 psi you must put in more air which means more weight but the shape doesn't really change? Is that right

Yes.

The proportion of the object that is submerged is the same as the ratio of the object's density to the density of water (around 1kg per litre). Density is defined as mass divided by volume.

An object of exactly the same density as water will be free to float at any depth (disregarding the very minute increase in density of the water itself at increasing pressures). An object of half the density of water will have half of its volume submerged. An object three quarters the density of water will have three quarters of its volume submerged.

So, keeping the volume the same (i.e., not increasing the size) and increasing the mass by pumping air, the density increases and the tire will sink further.

Why the hell are you filling a tire with air. You're supposed to use nitrogen, it keeps your dynabeads fresh.

Hmmmm. I have heard arrows being called missles.

According to the dictionary:


mis·sile
/ˈmisəl/
Noun
An object that is forcibly propelled at a target, by hand or mechanically.
A self-propelled or remote-controlled weapon that carries a conventional or nuclear explosive.
Synonyms
projectile - rocket - bullet

Are you sure you are a rocket scientist? If so, I hope you are not in charge. (JK)

Yeah, English is a b*tch sometimes.

I have also heard cannonballs being called missiles, but they are actually projectiles. They fit the definition you posted, though. "An object that is forcibly propelled at a target, by hand or mechanically." So does a thrown rock.


Hmm.

Hope I'm not in charge? Not in charge of the dictionary, this much is certain.
