True. My description above was for engineering stress (and engineering strain), I don't really think the OP needs the real stress to real strain graph..
The elongation is the current length minus the original length, not the current minus the previous.
Given that you've taken the load as the variable, and the elongation as the function of the variable, you get a graph of elongation as a function of load, and not load as a function of elongation. If you switch the axes (put the load on the x axis, and the elongation on the y axis), then it will...
A plasma is just positively ionized gas (by "positively", I mean that electrons are stripped off from the atoms, and not added to them, so the ionized atoms are positively charged). I'm quite sure there are ways to ionize a gas without heating it (shining a laser with the proper wavelength on it...
The calculations, as promissed:
Ok. I'll assume we're taking the approach of breaking the asteroid into lots of small pieces. The reasons for this are the following:
1. It would take much more drilling work than is required to alter the asteroid's orbit (since more matter needs to be chipped...
Well, at the basis, this could be as simple as a bunch of MEMS drilling/grinding devices. Although you'd want something more complex for a practical system, perhaps something more like MEMS versions of those huge machines they use for tunnel boring...
As long as you have a very large number...
It should be possible is to use nano-robotic devices to break the asteroid up into lots of tiny pieces. It's also possible to eject the pieces away from the asteroid as they are being chipped away, thus producing a small amount of thrust to nudge the asteroid's orbit.
edit: actually, we may...
20 mph is not that much...
So in other words we need more precise info before we can truly determine even the feasibility of a landing, let alone the benefits of it.
Yes, but if one object (the probe) is in orbit, and the other (the asteroid) is just passing by, then positioning gets more important, because their paths do not converge..
Why not? Is it a material properties issue or something more fundamental?
And btw, how fast will it be passing by...
Yeah, but the point is that we don't need to travel far to reach it, compared to the distances we cover more or less routinely. But it's true that we will need to match the velocities to land..
Although, it may be possible to do this:
1. Adjust the probes orbit around Earth such that the...
Hmm... this raises an interesting question. Before the tsunami reaches the coastal shelf, it travels as a pressure wave inside the water. How would that pressure wave affect the sealife that gets in its path? Is it strong enough to injure/kill some of them?
If I recall correctly, one of the videos on the web show (among many other things) a bird flying away as the wave floods the coast. So at least that one didn't leave the area in advance...
SAZAR, if you're referring to diagrams such as this, then I think you're taking things a little bit too litterally. This is just a 2D representation of how a light wave behaves. More specifically, it is a plot of the strength of the electric or magntic field that are associated with light, and...
