Sounds perfect, Gokul. Thanks in advance for help.

I am doing a quick calculation for preliminary design, and experimental method is not an option. I was hoping someone could provide a general value.

Hello, I am looking for static and dynamic coefficients of friction for bronze on stainless steel (dry condition). Closest thing I could find was http://www.engineershandbook.com/Tables/frictioncoefficients.htm" where it only has steel on bronze under greasy condition. Can anyone help me...

nvn, Thanks for info. Could you tell me what your source is..? Using allowable bearing stress seems to be a bit too conservative, as the allowable stresses defined in the standards that I mentioned are quite higher than those (2~2.5 times yield strength for USACE and 1.8 times ultimate...

Hi all, I am designing a set of side guide rollers for a vertical gate. There are four rollers on the gate (two on each side), and the rollers are designed for jamming load condition (they are not loaded most of the time). When jamming happens, one top roller and one bottom roller (on the...

Here's a picture of the problem. The shaft is supported at two points by diaphragm 1 & 2, and a downward force is applied at the left end of the shaft. The point of interest is whether the diaphragm is strong enough to handle contact stress between itself and the shaft, not how the shaft would...

I guess I should've explained my question more clearly: a shaft is under radial load on one end, and is supported radially on the other end by a hole in a plate. I believe the plate will be under some contact stress, and it will fail if it is too thin..? The fit between the shaft and the hole is...

Hello I am trying to calculate contact stress for a shaft on a hole. The purpose of this calculation is to see if the diaphram on which the hole exists is thick enough to handle the shaft radial load. Easiest approximation would be to use a simple formula for bearing stress (stress = force /...
