I knew it!!!!!!!!!!! I just knew that that would be the answer.

I'm beginning to think that I'm psychic.

The level of education is slowly coming into focus now, too, although it is difficult to see very much.

Just when we thouhgt things couldn't get any worse!

Do you speak to the members of you're engineering team as you originally spoke to us?

If I spoke to my team like that, I'd be in the first aid post having a broken nose set.

As a female engineer, I feel I am in the perfect position to explain PMS....

(sorry couldn't resist )

...more seriously, it is worth remembering not to talk only in acronyms, even when you have set the context.

I was going to use my X-wife as an example of PMS.

Don't know what the other two mean, but I'll bet the Warped Minds Department of CR4 can come up with some good guesses.

Dear friend it appears that you are new to this site.

First point putting a question in capitals irritates every one in this fourm as it is considered as shouting at the members.

Second before putting up a question surf google to know weather you get answers to your question

Thirdly avoid questions which give an idea that you are a student and asking for answers to your exam questions.

Forth from your question it appears that you do not have even the basic knowledge about the subject.

This is a site with mostly well experienced engeers from almost all over the world participate. Kepp all this in mind and follow the site you will get good results

Hope you have good time here.

Good Advice for new users and a GA to you.


Tips for Posting on CR4:

  • Look for answers before you post. Search CR4 or use a search engine to see if you can find the answer to your question.
  • Provide as much information as possible. The more details you provide, the better the chance that someone on the site will be able to help you find an answer.
  • Give some thought to your post title. Don't use "Hello", "Question" or "Help". Also, simply saying "DC Motor" is not enough. Be specific, e.g., "How Do I Install Replacement Brushes In My DC Motor". Keep it professional - post titles should be written in title case without excessive punctuation.
