Ask your tutor to do your homework for you and see what his reaction is!

How many points is this worth and how do we get the points assigned to our grades.

Also, do you promise not to work on any projects where my life would be in danger by the poor workmanship and poor decisions you will be making as a future professional that did not do his/her homework and therefore is not qualified to do his/her job?

There are lazy people that ask us to do their homework and then there are stupid people that ask us to do their homework. This goes beyond lazy and stupid. This steps into the realm of insulting. I honestly hope that this lazy bum is going deep into debt to pay for this schooling. That the failing grade that they'll get from this class will shackle them for years to come.

I'll give the OP credit for typing without mistakes. I think it was typed, not cut and paste, because there is only one misspelled word, label.

I doubt the original publication would have missed this.

Still, it's over the top, for sure.

I have to believe "lable" is one of most common misspellings in the English language. It's entirely possible that the text or worksheet the OP copied and pasted had it wrong to begin with, and the OP is too stupid to have used spell check, or even know what the little squiggly red lines under the word are in this forum posting box.

As I'm want to say when i see student postings like this:

You (the OP) must be a management student, not an engineering student, because your goal here seems to be to get someone else to do your work for you. An engineer would want to learn how to find this information in available resources.

<sigh>

If you did not pay attention in class then try an internet search, all the above answers to what look like homework questions can be obtained by an internet search.

CR4 is not a homework cheat site, and this appears to be university level homework.

Sure, here is a blanket statement from the moderators of the CR4 website that sums it up nicely.

http://cr4.globalspec.com/faq

What is CR4?

Conference Room 4® (CR4) is a forum for engineers, scientists, technical researchers, technical buyers, students and folks who just like technology to discuss engineering news, seek technical help and get answers to burning questions. CR4 is a community site supported by GlobalSpec, the Engineering Search Engine.

Are there specific rules for posting?

Do your own homework. CR4 is not a homework cheat site. While some here might relish the opportunity to sharpen up old rusty skills by working the homework problem, consider this and consider it well. If you cheat on your homework by using someone else's answers, you are only cheating yourself, because the purpose of any homework or other college assignments is to help you learn - by practice, repetition, and self-discovery.

How much clearer can we be, CR4 is not a homework cheat site and we are not here to answer peoples questions.

Are you the 'Guest' poster of the original question?

You are not definitly helping the world to develop.Are you afraid of brain drain? Or Are you trying to be a good citizen to follow some rules which are meaningless at some instant?

Q21: what's in it for any reader to respond to such a list?

The original poster is being lazy and is disinclined to carry out basic research to answer these questions.

Ans so should the potential respondent.
