Now, here in this question, you are giving a number of solid materials, and you ask to look at four possible ways to change the characteristics with the materials, and look at the different way, look at how the material actually responds, right? and for example, you look at stone.
00:20
Stone, can you bend it? no, you cannot ban it.
00:22
How about hammer? it can hammer it, but you break.
00:24
So you cannot change the characteristic of stone by band or hammer.
00:30
Price.
00:31
A price you can press, but you won't change it because it's very hard.
00:34
You can cut it and change shape.
00:35
That's true.
00:36
How predate them? you can not really ban it.
00:39
You ban it.
00:39
You just break it.
00:40
But you can hammer it.
00:41
You can hammer it.
00:42
You can hammer it, quickly, you know, it does not rest in strong shear force, right? don't hammer it.
00:48
Press, you can press it and you can deform it, right? you can cut it as well.
00:53
So how about eraser? eraser, you can ban it to a certain extent, right? you can ham it.
00:58
No, you don't really hammer.
00:59
You hammer, you just break, right? and press, you can press it.
01:04
It appears a bit harder.
01:05
And cut, you can cut it, certainly.
01:07
Sponge.
01:07
Well, sponge, you can bend.
01:09
You can hammer, actually.
01:11
You can kind of hammer, but, you know, it's likely, you're likely to damage it.
01:16
And press, you can press.
01:17
You cut it, because you cut it as well.
01:19
A copper wire, you can bend...
