can these detect displacements in microns??

we manufacture 1.2 mil. of these in a month. we use a vision system for checking missing needles. it is difficult handling such large volumes. also vision systems cost a lot of money

that cam roller is basically a needle roller bearing

I am a quality control engineer in an automotive parts manufacturing company. One of our products is a rocker arm bearing which is essentially a cam follower. The OD and ID of the bearing is ground using CBN grinding wheels. The ID contains cylindrical rolling needles. Recently we have received...

Dan S thank you. This is the answer i was looking for. It is a very simple reaction vessel

How can I calculate the pressure exerted by a fluid on the walls of the vessel that is being agitated. The vessel is not pressurised. I have to calculate the resultant pressure on the walls to calculate the thickness of the vessel walls.

can the thickness of the head be different from the thickness of the shell

I have to model a storage vessel in ansys and perform stress analysis for it. I have no idea about which element types I will need for the analysis. I have calculated the design dimensions for the vessel. I am a beginner at ansys and know only how to deal with simple structural and thermal...

A pressure vessel

this is an academic exercise

I have been asked to design a pressure vessel and the data given to me for the problem is - content -oil of density 0.9 g/ cm3. material with ultimate tensile strength of 70,000 psi. factor of safety 3. volume 50 m3. How do I calculate the internal pressure and diameter, which I will need to...
