    Why do fish die under an oil slick?

    Well if someone wants to perpetuate and agenda. Then most likely they would add something to the oil spill to cause the fish kill. Funny how no one worried about it during the big one WWII. My mom told me about how she constantly saw the thick oil on the beaches of the east coast. From all the...

    SHAFT ALIGNMENT TOLERANCES

    Depends on how the shafting is connected. Like in automotive applications it isn't real critical due to the use of universal joints. To lessen the power losses and wear, the closer the better. Especially if it is a solid connection, if it isn't real close then something has to take up the...

    automotive engine performance

    I think most auto manufactures proof test their engines at max rated HP for X amount of hours. To run full rated HP as continuous you would need a cooling system to handle it. And most likely some other type of exhaust system. Since there have been many automotive engines converted to...

    Why machine brake rotors?

    Well I have like 60,000 to 70,000 on some brake pads and shoes that were only supposed to last 30,000 or so. And that is on the NONturned drums and rotors. Also in my flying days, the small planes that I rented had rotors that were grooved and worn worse than anything you would want to use on...

    Jet and Turbine emissions

    I have found refferences on the net about how the EPA and State agencys had stopped worrying about emissions from Jet aircraft because for the 5 year period no headway in reducing them was insight. I would like to see some figures on what types and what the quantities are of the various gases...

    EGR and how it adds to fuel economy???

    I guess soon the blower on a AA fuel dragster will be replaced by an EGR system.

    Ultrafine Particles

    Good news, maybe this will be the end of turbine and jet engines. Must be my natural hate for them.

    The Tragedy of General Motors -- Fortune article

    Its really pretty simple. Back in ole Henery Fords day, he had one old secretary that did everything. Book keeping, payroll etc. Now most all big business keeps adding thousands of "non producers" that usually make more than the worker in the factory. So there is a lot of non producing over...

    Simulating control buttons on CNC machine

    It isn't so much a practice how to use the buttons type of deal, when operating CNC machines. Its knowing how to use the work offsets, setting cutter comps etc. A good CNC book can explain that to you. All the various controls are different in how they accomplish the same task. If you know how...

    Shaft fracturing

    350 in lb ???? And its .5 inch diameter? So that undercut area must be a very small diameter. I could not access the photos. I would like to know what the torque requirements are for the compressor and "various speeds"? What is the instantanious shock torque and full governed speed? And...

    Different cam profiles on the same engine?

    I think that is one of the secrets in some racing engines. I read some place that some stock car engine builders have been doing that for years. To compensate for different induction flow charateristics, and other cyl to cyl variables.

    Coasting in N with engine off

    The major difference between and automatic transmission and a manual. Is the type of bearings used. Most manuals use frictionless bearings, ie ball bearings generally. And they will live much better with minimal lubrication. In the automatic, it has mostly plain type bearings or bushings. And...

    Engine Rebuild, Electrolatic Corrosion?

    I have used stainless steel studs, bolts, nuts many times in that sort of application. But not copper no strength in them. Just make sure you use a stainless that won't rust. As some species do.
