What is the difference between an elastic & inelastic materials?

Elastic materials spring back to their original shape when they are stressed. Inelastic materials simply bend and stay bent, which is called plastic deformation.

because they use different material than each other

If something weighs about a ton you will need much inertia to stop the object. If you have a marble and you want to stop it you need less inertia. So inertia is force needed.

As the temperature increases, the stretching of the rubberband will increase. This is because there are intermolecular forces between the fibers of the rubber when it's unstretched. When it's heated, the particles start to vibrate more thus they expand. This causes a decrease in the magnitude of intermolecular forces so it will be easier to pull it now, same as it does in melting. This cause it to be more elastic.

Faster plasticity\n\n.

Plastic vs. Glass\nfirst off it isn't too fair to compare plastic to glass. You're comparing a category of materials against one single material. Plastics have almost an infinite range of properties where as glass has one set of properties. There are some plastics such, as acrylics, that behave very similarly as glass with respect to impact strength, clarity, etc. And there are some plastic that behave nothing like glass. Such as polyurethane, very ductile and rubbery even. \nTo conclude, depending on the plastic there can be many differences between plastic and glass, or they can be quite similar.

Looks like you are reading the book only. sometimes you have to get into some experiments, lab work to get better understanding.\n\nMechanics is the most Important part of physics or any dynamic structural analysis. To get better unserstanding ask your teacher to give you real time examples to solve.\n\nIf you do not understand the basics of Mechanics of materials, you'll have hard time to understand the properties and the analysis part in the future.

There are specific eqn's used to determine the point at which an object will go "plastic" and then break. It is determinant on the radius and composition of the object. You have to look at youngs modulus and the tensile stress being applied to the object you are using. here is a table of some values for Youngs modulus and tensile stress: http://cougar.slvhs.slv.k12.ca.us/~pboomer/physicslectures/textass/tables7-8.jpg\n\nThe Young's modulus allows the behavior of a material under load to be calculated. For instance, it can be used to predict the amount a wire will extend under tension, or to predict the load at which a thin column will buckle under compression. Some calculations also require the use of other material properties, such as the shear modulus, density, or Poisson's ratio.\n\n\nLinear vs non-linear\n\nFor many materials, Young's modulus is a constant over a range of strains. Such materials are called linear, and are said to obey Hooke's law. Examples of linear materials include steel, carbon fiber, and glass. Rubber is a non-linear material.\n\nYou can find this kind of table for most household items, and since you are using fishing line there are different "tests" which will hold various ammts. of weight before breaking.. Ie. such as a 100 pound test will hold that mush weight as opposed to a 20 lb test which would break pretty easily. You could vary the test weight on various strings and by knowing the test you could predict at which time the string would break...

Creep is the distortion of a structural element when stressed beyond its elastic limit.  If you bend a paper clip a little bit, it will spring back to its original shape.  Bend it a little farther, and it won't -- that's creep.\n\nMaterial fatigue is the weakening of a material exposed to stress.  It is not ordinarlily a problem if the material is not stressed beyond its elastic limit, but if it is repeatedly stressed to the point of creep, the material may be weakened sufficiently to fail.  Back to the paper clip -- bend it back and forth a few times, and it will break.

When a material specimen, like plastic, is undergoing a tension test, eventually the tension exceeds the strength of the material to retain its shape. The specimen stretches, but since it must conserve volume, it gets narrower too, which is pretty intuitive. That's called necking, especially when it happens at one place in the specimen. Brittle materials don't deform like that - they just snap before becoming elongated. Ductile materials deform significantly before breaking (by necking). That's what Necking is... now... what other measure of ductility would you use? Brittle materials have a pretty linear stress-strain relationship that ends abruptly with fracture. Ductile materials start to strain more, producing a stress-strain curve before failing. Isn't that just another way of measuring the same effect, deformation prior to failure?

Well, a clear question would help. \n\nAre you trying to calculate the power that a certain material can withstand?   Or are you trying to calculate strength?

You question is incomplete....or at least requires more information, as it is, it is too general.\n\nWhat are the conditions are are talking about here?\nAre both balls pushed with some constant force?  As they rolled down an incline?  Are they already in motion?\n\nWhat type of surface are they on?  A smooth (frictionless) surface?  A rough surface where friction needs to be taken into account?  Are both balls solid, hollow, one each?\n\nThey are many many variables which need to be taken into account, you cannot just say "big" and "small" and get an accurate answer.\n\nAnd by "greater distance" do you mean translational displacement, or angular displacement?

Yes, they are different.\n\nElasticity of demand is the change in quantity demanded associated with a change in price.  This is the slope of the demand curve.  This slope is always negative.  The lower the price, the higher the demand and vice versa.\n\nElasticity of supply is the change in quantity supplied associated with a change in price.  This is the slope of the supply curve.  This slope is always positive.  The higher the price, the higher the supply and vice versa.\n\nLet's take a simple example.  Movie tickets increase by $1.  As a result movie attendance decreases by 10%.  The elasticity of demand would be -0.10%.  For every $ increase in price, quantity demand drops by 10%.  However, given the same increase in price there is a 20% increase in movie showings.  For every $ increase in price, quantity supplied increases by 20%.   \n\nFor any business venture, you have to price your product and services with a good understanding of the elasticity of demand.  Depending on such elasticity, it does not make sense to increase price beyond the point where your revenues and income break even with where they were in your original price structure. \n\nElasticity of supply deals more with the operation structure of the industry you operate in and external competition. \n\nIf you want me to clarify any of the above, please contact me through "Answer."

Intensive properties do not depend on the sample size whereas extensive properties do.  An intensive property would be the melting temperature which obviously doesn't depend on sample whereas an extensive property would be something like volume, which obviously depends on how much stuff is present.

both.  the friction, as well as creating its own heat, slows the airflow, which aggrivates the compression along the leading edges.\n\nI'm pretty sure.  don't put this on a physics test and then blame me.

Which depends on the stres acted on the load and material used
