A material is a substance or mixture of substances that constitutes an object. Materials can be pure or impure, living or non-living matter. Materials can be classified based on their physical and chemical properties, or on their geological origin or biological function. Materials science is the study of materials and their applications.
Raw materials can be processed in different ways to influence their properties, by purification, shaping or the introduction of other materials. New materials can be produced from raw materials by synthesis.
In industry, materials are inputs to manufacturing processes to produce products or more complex materials.
Here is the question that is is given to me
Part a:
Part b:
I have given this a go and was wondering if my answer seems reasonable.
I had worked out that the mass per unit length (mu) is also the density * cross sectional area of wire
Thanks!
so I have quickly gone over this, but feel that I am not going in the right direction.
I am assuming Y = 1 so,
62 = 164 sqrt Ka
given UTS = 164 Mpa
Kic = 62 Mpa m1/2
therefor,
working for ac, (the damage tolerance of the material)
Oa = UTS = 164 Mpa
Kic = Y Oa sqrt ac
62 = 1 * 164 *...

I can create a fairly strong magnetic field by leading current through a copper coil. However, I cannot then with that magnetic field create a current (not a useful one at least) in an object made out of copper. I understand that this is because copper lacks of magnetic properties. For instance...

There are two questions that arose in my mind, first of all tokamaks use toroidal field coils which create a toroidal field within the torus to shape the plasma and confine it, but here is a question, the toroid coils have a static B field produced from a DC current in them, what kind of metal...
I have read some materials about quantum hall effect and know that at the edge of a 2D material , one can linearize the potential V and the linear dispersion relation represents right/left moving fermion. So , Can I say that for a given hamiltonian , if I can linearizae it at edge, then this...

Hey guys, so I have to give a 10 minute presentation for my class. I am absolutely terrible at memorizing stuff. Its pretty bad. If I can find an interesting or cool topic I would be able to remember material better.

I find it really interesting that I can look at an image of rubber and know immediately its rubber, and then look at an image of a metal and know its a metal. How do we reach such conclusions? My first guess is the smoothness of the material's surface, but maybe there's other features I'm...

For the past few weeks, I have been trying to review the math courses I've taken over past two years. All I can really do, though, is just read over the chapters. I acknowledge that the only way to actually (re)learn the material is to do the problems. I always tell myself that I can do it in my...
I need a wax like material I can buy that I can paint onto a surface and then have it harden on it's own. I want to create fine details on a plastic model, so I would coat the model in wax with a brush, have the wax dry, and then sculpt out the details later.
My ideas so far are wax for waxing...

Hello All,
I'm curious if there is some chemical or clear / semi-clear material that will absorb or deflect infra red light in the 890 - 910 nm range.
IR absorption would be ideal, but deflection should work as well.
The idea is to prevent reflection of IR back to it's source.

In electrostatics, for what I understand the when I have an electric field, the density of the energy stored in it is given by the following formula:

Is this correct?
