I guess this should go in this forum because I am out of school. Anyway I feel as I have a slight problem right now. I am 27 and have a BSME and a MSME but do not currently work in my field. I am lacking relevant work experience and didn't take advantage of certain things while in school. I am...

I have a bachelors and masters in mechanical engineering and am wondering how necessary the PE license process is for progression. I have not taken the FE yet (but will this year) and feel it would be the next thing to help me progress. What is your feeling on this? Have you personally found...

nothing?

First, hopefully this is in the right section. So I am looking for the best way to prepare for the new FE Mechanical exam. I know that the format changed in January 2014 so I am having a hard time finding the best books and study materials for this new format. In Google searches results come up...

I also need that the oring kind of centers the tube but am open to other methods. What would you recommend?

I am looking for some info. I have two hollow tubes that need to slide into each other and have the inside one not fall out due to friction from the oring INSIDE the larger one. It is not doing any sealing, the oring is just to cause friction. The inside tube will be moved to remove and replace...

ok using p1v1=p2v2 i did this p1 = 4500psi + 14.7 psi - 4514.7 psi v1 = 253.859 ci p2 = ? v2 = 253.859 ci + 68 ci = 321.859 ci so p2 = 3560.9 psi and that is 3546.2 psi guage.

I should have mentioned it is compressed air so all gas. Wow I know boyles law but didn't think to look at it as the volume is increasing as it is connected during filling but was thinking it is "removed" since it is leaving one tank. That clears it up a bunch. Yea I knew the wording was wrong...

i understand that but i want to try and figure out what each fill would be with no compressor. i know it won't make sense to do this in real life but now it is bugging me because it seems so simple so figure out the pressures yet i am not 100% sure if the math i am doing is right.

Ok I am wondering how to solve this or go about figuring it out. This is what I am trying to do. I have a 253.859 cu inch tank (tank A) filled to 4500psi. I want to fill 68 cubic inch tanks (tanks B) with it. I know that after each fill tank A will decrease in pressure by a little amount and...

Thanks for the reply. I figured it would be pretty difficult to get an exact answer. My concern was not whether it would last as I know it would last hundreds of thoudsands of cycles (the application is not something groundbreaking or new). The thing is some people have come forward with...

not sure if my title is the most accurate but here is what I am asking. I will give general dimensions and weights in case it makes any difference. **EDIT** This is a pnuematic gun if you couldn't tell and if it makes any difference.** You have a hollow aluminum tube ~7/8" I.D. Inside the tube...
