    Scavenge pump for hydraulic oil.

    Hello?? Anybody here to confirm?

    Scavenge pump for hydraulic oil.

    Ok so im having a bit of a problem with calculations. I have a piece of rotating machinery I am putting this pump on and the pump is at the full 3 meter radius. The pump will be subjected to 100g conditions. Now not all of the 3 meters to the center is subjected to 100g however. The normal...

    Scavenge pump for hydraulic oil.

    I need to design an oil scavenging system for the output of a hydraulic system. The flow is not very much perhaps 0.1 GPM but it is hard to establish the flow rate. The source of the oil is the output of two servo hydraulic actuators, and their hydrostatic bearings. The flow of oil is not...

    Yield or Tensile strength for calculating parts

    I don't even know what ratcheting IS. Nor do I know if this persons widget is a plate or a platypus. Anyone can add complexity to an analysis, it is quite easy to do. What about corrosion? thermal cycling? Stress concentration? Hydrogen embrittlement? What if the sample is not uniformly heat...

    Yield or Tensile strength for calculating parts

    I'm not sure why no one has provided the simple answer to this question. Stress>Ultimate = part broken. Stress>Yield = permanent deformation. You would apply your "factor of whatever" to the yield strength in most cases because your design most likely would be changed by plastic deformation...

    Cylinder Design: Bore and Stroke vs. Flame-front propagation

    Question for owners of the HARDCOVER Heywood engine book... Are the illustrations in COLOR? I was going to pick up the MUCH cheaper paperback version, but since it is in black and white, i didn't want to lose any graphical information it may contain. Thank you.

    Cylinder Design: Bore and Stroke vs. Flame-front propagation

    Well I see the Heywood book getting referenced more and more. Clearly this is the Go-to reference around here. Are there any other books that are of this caliber that I should know about?

    Cylinder Design: Bore and Stroke vs. Flame-front propagation

    Not only did I not take offense, I appreciate the link. I have added the book to my cart. My background is in mechanical engineering technology. I have a concentration in fluid and thermal sciences as well as stress analysis. In my personal life I am completely fascinated by automobiles of...

    Cylinder Design: Bore and Stroke vs. Flame-front propagation

    Who is heywood? My linear combustion speed are you referring to the propagation of the flame of the piston speed?

    Cylinder Design: Bore and Stroke vs. Flame-front propagation

    So I have been thinking a lot about the mathematical optimization of cylinder geometry lately. I seems as though the intersection point of flame-front propagation and the dynamic stresses for a standard gasoline engine yield a cylinder volume of around .5 liters. Obviously low speed engines...
