what is criteria for coupling gaurd material ,and other characteristics?\n\nif you have any information regarding coupling gaurd i will be glad if you share with me.

Depends\nI would say a a cast ductile iron piece would work on a small pump and motor assembly .  How ever more info is needed. Knowing the motor Horse power and shaft length. Mainly you are covering the shaft so accidental contact can't be  made by a person,,, But if you are needing it to also protect against flying object if the shaft breaks,,then thats going to change a few things

Following-up Letter (Please correct the following letter or sentences if there is any mistake) ..thanks!!?\nDear XXXX \n\nI would like to follow up on our explosion drawings of October 10th. Please review the attachment to see the updated explosion drawings we have prepared. We look forward to your comments and learning whether or not they meet your needs. Thanks for your time and consideration.

how about something that has to do with what the best powder for lifting prints is.\nthe hypothesis could be:\n______ powder is the best for lifting prints. does that make sense?  that way you could talk about all the advancements that have been made on the powders over the years.\nfor example lead powder vs. carbon powder.

I will try. \nNot because it is difficult to understand but difficult to describe. Let us take a three member truss.\n\nA truss must be in equilibrium otherwise it will fall into its three component pieces. Lets assume it is for a roof\n\nFrom its apex to the two walls its load will come from the tiles, and for these the angles and weights are calculated to establish what portion of it goes to which joint.\nThe two portions at the top are examined together to make sure their loads will be stable against each other.\nThe portions at the bottom are being supported by two walls but they have two components each. One wants to rest on the wall while the other is trying to move away from the wall.\nTo keep this from happening we have to introduce our third truss member and make sure it can take the tension required of it.\nNow we know all the points we can show the summation of all the loads and ascertain if they are in compression or tension.\nWhen we have selected or designed each of our truss members we can fix them to keep the whole assembly stable.\nNow the truss it in equilibrium.\nTry it with large match sticks and think of what you are reading.\nIt might help.

lol \nYou have homework that you don't know the answer to.  \n\nWhy would someone ask these here out of interest? Like you have these specific parameters and conditions that you are just raring to want to know just out of the blue.\n\n Quit wasting time writing and typing questions out waiting here for answers when you could be the next engineering graduate who actuallly UNDERSTANDS this stuff by doing it yourself.

Steve Gibson has some great examples and utilities.\nhttp://www.grc.com/smgassembly.htm

I have a drawing that shows the various types of shell and tube exchangers. I believe their functions are self evident if you see the cross sectins.\n\nSend me you email address and I'll send the drawing.

If you want designs that are "unique in physical appearance," you are pretty much constrained to building them around the standards for the spacing, length, etc...that would make them compatible with all other plugs and outlets. Once designed, it is a good idea to get them UL Approved.\n\nThere are no "universal standards" - if your target market is the United States, you would simply conform to American standards - there are different configurations, voltages and standards throughout the rest of the world.\n\nCheck out:  www.nema.org/standards

ok--i'm not completely sure about this--but i can at least try-- *cough cough*unlike some people*cough*cough*catweazle*\n\nwe did this type of stuff last year.  but i think that you might want to use the ideal gas law?? we always called it pervnert... PV=nRT... does this sound familiar?    \n\nif not, i suggest asking your teacher, or some other knowledgable chemistry person.\n\ni hope this helps!

Good ? fernando,\n\nI thought about this problem and remembered blowing up balloons long, long ago in my childhood.  (It actually is easier to blow when the balloon gets larger).  \n\nReason: the material stretches in the larger balloon and becomes thinner, so the elastic modulus is inversely proportional to size.  Ergo, when the 2 are connected, air will flow from the smaller to the larger, since the smaller one has more pressure.\n\nI realize this is not a formal proof, but it will have to do for now!

I've worked with flowmeters for 20+ years and have never heard of this... what medium are you trying to measure?

Congrats, I am working on my thesis too.  There is PDA (potato dextrose agar), V8 agar (made from guess what, V8) and many others.  Each is designed for a specific purpose.  I am not an expert on this, but try a search engine.

Can you be more specific? Every material has it's own index of refraction....and none of them work out to nice even numbers. (well, hardly any of them). Is this all the questions says? I looked around on some websites, none of which made this question any clearer. Good luck!

wow, that's really interesting. I'm gald i read the whole thing, thanks for putting this up here. Where did you find all this information? I'd love it if i could look into it even more, or if you could do some more research and put your findings up here again.

when ever two dissimilar metals are joined  they produce a specific millivoltage at each degree of temperature\nif you graft the changes you will find a bell curve \nunique to each type \nthis is how you determine which is proper one for your use\ntype K alumel and cromel  is used at medium temperature ranges 90 to 1600 degrees F
