This is the nearly pure metal molybdenum, not moly disulfide. We are introducing well filtered machine oil via an air-oil system down at one end of the bar, where the steel bar is in a steel bore. It is reported that the bar was damp with oil at the other end, where the steel bar is in the...
We have a hardened 8620 steel sleeve with a steel shaft keyed inside it, so there can be sliding motion but no relative rotation. The sleeve is relieved in the middle so there is no contact there. ONe end of the sleeve is sprayed with nearly pure Molybdenum on the ID and ground for a sliding...

-Is there any inherent advantage to having the natural frequency above the driving frequency? If I look at an output magnitude vs. driving frequency plot for a 2nd order system, the magnitude drops off at frequencies above the natural frequency, but I was taught that higher natural...
Hi Evelrod !
"Given any kind of choice at all, no one in their right mind uses Detroit Locker."... was a quote out of one of Carroll Smith's books.
I was not sure if you thought I was saying that. I would have phrased it differently, even if I thought it, which I would have no...
Is the lube pressure fed thru the crank via the main bearings? If pressure fed, there are right and wrong locations to introduce oil for a particular crank rotation, and allowing alternate rotations is not helping matters any. A groove in the final destination bearing is pretty bad too...
Hi -we need to run a large motor - The motor is 460 Volt 3 phase 4 pole squirrel cage asynchronous with a built-in encoder. The encoder's output is 1 Volt sin/cos.
We have a nice vector drive, but it only accepts TTL or pulsed signals from motor's encoder.
I suspect there is a simple device...
Financial issues overcame my principles, and I put a pair of MAxxis street tires on my old yamaha 850. They have a tighter curvature than the Metzler laser/worn Kenda that were on there. THe contact patch is MUCH narrower at both ends, and vaguely triangular at the front. I would not...
No personal experience with SW 2003 yet, but I justed wanted to say in general "uninstalling" is NOT the same as the havoc-wreaking act of deleting program folders etc.

no thermal expansion specs there, but shrinkage on the order of 7% appears fairly typical. I wonder if the residual strain from that much shrinkage might be more important.

I think you need to find your way to the bearings engineering tech dpeartment. I have a few...
If an accelerating 100 inch wheelbase vehicle's nose rises 4 inches and the tail drops 4 inches the difference between a horizontal vector and the vehicle CL (error?) is about 0.3%.
some folks claim good results and swear by the hot rod toy GForce gizmo.
Coolant always circulates thru the block. If it did not, there would be severe localized overheating long before the thermostat got slightly warm. So, I'd say the thermostat's job is to decide how much of the constantly circulating water should be fed thru the radiator.
Fairly well balanced stuff exerts less than 10% of it's own weight as "centrifugal" force on rigidly supported journals. A Cevy 350 V-8 crank with radically different components can be out of balance several hundred gram-inches as measured at the end counterweights. Spinning a...
fatigue symptom = pitting or craters? pictures here

full bearing width or toward one edge? ever seen cavitation damage on a pump impeller?
what's your oil temp?
We have trouble making decent autocad drawings from SW drawings. I read Tick's post about flaky fonts and GED info. Those are some of our exact problems. I am about to try saving as older versions of acad, maybe as dxf instead of dwg, and using acad fonts. We have yet to try the mapping options.
12 inch deep water is 62.4 lbs/SF.
I think my rafter tables were based on span/something max deflection with max stress in parentheses. The few buildings I have seen collapse were either damaged from rot or not built to code.
What are you using as evidence that there is less rear downforce at speed? Oversteer could be more front downforce/less front lift. What do yarn tufts do over those rear deck vents ? Tape a scale to the rear wheel well opening and Get a buddy in another car to take pictures to see if the...
