I been looking all over for a aluminum or steel tube that is at least 18 in long The ID of the tube will be anywhere from 8-12 inch with a 1/4+ wall thickness. I been looking all over the place and can't seem to find this. I have asked the metal shop guys and they are not sure since they...

Thank you for the heads up. I will talk to Barden. The funny thing is that the engineers at my sponsor gave me a set of Barden Precision Bearings. The ID is .5 inch but they are older bearings and I cannot find any information on that. Thank you again, back to hibernation to figure this...

Here a quick update, We came to the conclusion that it is not within our budget to go 30k+. We were given a electric motor the is rated at 22k ( not sure of the voltage) and electric fan bearings that are sealed and almost matches the speed. The bearings so ceramic type bearings the ID is .47...

wow that is a lot of stuff but great information, I will have to get back to you on this stuff as mid terms are here. Thanks you for the help, I will update on this once I get all my research done.

here is a picture of the item. It is the red part of the picture. The shaft size will be 2.5 inches. Air would be entering the shaft in the middle and exiting out of the green cylinder (thru a venturi, not in pictured). The shaft would be rotating at 30K + rpm. There will be bearings on both...

Hi, everyone I am a long time reader but this might be my first post. I am currently in a Senior Design Project and doing research for my project. I am doing a rotating shaft with flow through the middle of the shaft to a exiting hole on the other side radially out the shaft. ( I can explain...

A rocket is 1.00x10^10m from a moving star moving at a speed of 1.00x10^5 m/s with a total energy of -1.67x10^17 J when it experiences a gravitational force magnitude of 6.67x10^7 N. It turns on its thrusters and its speed as well its distance to the star doubles by the time the thrusters are...

thanks this is a great link, Any other ones? The more the merry as repeative learning help me a lot.

Does anyone have some links to some great physics demonstrations on the first part of classical physics. ( Mechanics) Thank you I am trying get a better understanding of the subject.
