Hi, I apologize if this isn't the right forum for this. I tried to pick that which I felt was most appropriate. My question is about 'flat flex cable'. Somebody I know recently purchased an A/C unit which uses a flat flex cable to connect the control board to the motor and such. They would...

Hi, Can anyone recommend a good adhesive to glue a strain gage to steel? Ideally it would be something readily available at a hardware store or something like that. The expected strain will be approx. 10%... hopefully less, but possibly slightly more. Thanks!

"Yep I suppose you could, but the real question is why would you want to? What is interesting about the flow in free air after a duct?" Well there is nothing interesting in particular. That was just an example I came up with to explain my question. It had just occurred to me that there must...

I do realize that Reynold's Number is not a property of the fluid.. but is dependent on the fluids properties. My confusion comes with determining the Reynold's number in an open environment such as a room or other open space where there are no defined boundaries where the flow exists. So if...

Hey guys, I'm looking for a little help understanding Reynold's Number. I know that its the ratio of the inertial forces versus the viscous forces. With that being said, everywhere I look, the Reynold's Number is calculated for flow in a pipe or duct or across some sort of surface. Why can't...

Homework Statement Hi everyone, This problem concerns calculating Reynold's Number of flow after exiting a duct. The duct that the flow exits is rectangular. The flow is measured directly underneath the center of the duct at a distance of 10 cm below the exit (Y-axis). Flow is measured...

Thanks. I'm really just looking for a rough estimate of friction, but I was mainly looking for input just to make sure I wasn't overlooking something too major.

Since there have been no respones, should I assume that my logic is reasonable? Or just nobody has a decent idea about it either? Any input would be appreciated. Thanks.

Homework Statement I'm trying to determine the friction of a pin joint that will be loaded differently depending on the position of the linkage. Homework Equations I know the equation for frictional force is F="mu"*N, where "mu" is either the coefficient of static or kinetic friction...

Homework Statement Basically, I am looking to find the reaction forces at the pin joint on the right side of the structure. I just realized it is not labeled on my diagram, but it is the pin on the link opposite of E. Where the 13 degree angle is measured from. Homework Equations I have...
