I posted this in the mechanical fluid power section, but figured I would cross reference the post here as it is an automotive application.

I have an idea that I'm trying to see if it is practical to implement cheaply with off the shelf components or semi-custom components (i.e. custom cylinder stroke). Don't want to get into too much detail on the application, but the fluid power will come from engine oil with a minimum operating...
I have 11 years of experience and have been working contract for the past 3 years as a mechanical/ocean engineer. I spend about 1/3 of the year traveling, mostly oversees typically a month at a time and the rest of the time working from my home office. About 95% of my work has come from one...
I'm working on a problem dealing with buckling on a short shaft with combined compression and side loading. The slenderness ratio is only 10. The side loading can be significant (as much as 1:1), but as the compressive load goes up the side load decreases. I haven't been able to find a...
I am trying to find some guidelines on designing a "hard" gate for an a-frame so I can verify a new design. Many of our clients have started to refuse equipment with chain or wire for handrails and gates. Because of this, I came up with a very simple 4-bar linkage that folds up vertical on one...
I have a supplier in Singapore that is having a hard time finding various size wide flange beams in low temp rated material. He has come back asking to fabricate the beams instead out of ABS EH36 material. This plate material is already approved by us and is used for many of the plate...
I have the rare opportunity to test a couple of old a-frames to failure. These are old a-frames that have been inspected and determined to be unfit for refurbishment due to a combination of weld cracks and corrosion. I have been asked to predict the theoretical failure load of these two...
I have a very good article from the Copper Development Association regarding bronze bearing design. They recommend a press fit of H8/p7. For a 165.1mm (6.5in) nominal bearing OD I have calculated a hole limits of 165.163/165.1 and bearing limits of 165.183/165.143. If you take the smallest...
I need some help finding some reference material on how to calculate the stress in the flange of a c-channel due to a roller. We are using a c-channel made from plate as a track with a straight roller pressing on the flange. I'm concerned with the stress on the flange causing a failure and the...
