Kelly, Unless I missed it... very possible... We could use a horse power requirement calculator, with related calculations. This should be workable from neutons, miles per hour, kilometers per hour,.... tons, lbs, kilograms... etc. Thanx..

Hydraulic HP=PSI * GPM/ 1714 * pump efficiency Neither your pump nor motors will be 100% efficient-as you probably know start from your load and work back-always cheaper to overcompensate than design a overloaded/low bidder contraption. Hope this helps, Maytag

I was just thinking about that. We actually have a bunch of related knowledge, see below. However, how the H! does anybody know where to look or what to search for? Additionally, the content may seem to only be related to electric motors, where much of the equations will work for other systems. How would you direct folks to these critical knowledge areas? /motors/sizing_electric_motor.htm /motors/torque_electric_motor.htm /motors/fans_blower_horsepower_equation.htm /motors/linear_motion_horsepower_equation.htm /motors/rotating_horsepower_equation.htm /motors/accelerating_torque_force_equation.htm /motors/solid_cylinder_axis_torque_force_equation.htm /motors/hollow_cylinder_axis_torque_force_equation.htm /motors/linear_motion_torque_force_equation.htm /motors/speed_reduction_motion_torque_force_equation.htm and a menu for electric motor stuff: /motors/motor_menu.shtml

well.. the binary choice tree search with the viewer making a few choices is the best thing I can come up with... .. so far. Actually, with your knowledge base to tweak it, I think that may be a realistic (but labor intensive) solution.

I agree with your thought process. Ultimately, with a web site (and life for that matter) is about choosing the right words. When I create an article or technical web page I work hard to title the page such that most folks can find that web page by search engine on those search keywords. It amazes me how many words one could choose to search for something. When I look at the referral logs as, well as, the internal search script logs I see thousands of different keywords - mostly single or two word phases. There are more popular words however, none are dominant. Also, Engineering, design and manufacturing professionals use different words to find identical or similar knowledge. A solution is to enhance my search scripts to identify by multiple keyword phases. A robust and smart internal search script is probably our best chance of getting folks to the right information. Unfortunately, these things are expensive, and I doubt I can write a good one cost effectively. I am aware that Engineers Edge search scripts are imposing significant load on the servers when many searches are conducted at the same time. This tends to cause big slow downs, particularly at peak traffic hours. I estimate, that we will be forced to use a different search script by the end of this year. In general, his forum has been the best source of finding solutions. If a question has been asked enough, then the right words are available, and chances are, a link from that forum message has been posted. Should we create a "Hot threads" or "Popular questions" reference page on this forum? Would that be helpful? Modified by Kelly Bramble at Sat, Feb 17, 2007, 09:02:32

Yeah... I like the "most popular" idea, but,... perhaps with some kind of qualifying.. 'otherwise the threads rising to a popular level may sometimes be ones that are expressing attitudes(sp) and not necessarily those that are informitive or are providing evolutionary enrichment to the world wide knowledge base. .... one noticed trait... you are gainging some darn strong mental strengths and educational depths through your management efforts of this web site. As a result of effort and apparently good goal setting (and milestone achieving) Engineers Edge continues to become increasingly both more powerful and useful. The very fact that it is difficult to manage the vast amount of data in the most searchable and useful manner is a testiment to great growth gains. Keep up the good work and efforts, there is no telling how large a part of the world knowledge base this can truly become. The curve is most certainly on the up swing. A "most popular" section would clearly contain most sought after subjects. Therefore it would by definition be a less complex section to write a search log specific for.... (because the less popular subjects would not clutter it) and as a result perhaps become an increasingly more important answer base... heck, one thing for sure, it would be a huge quantity of brains "think tank". Wow, and that has tremdous, unlimited potential. ...so.. yeah. you should try a "most popular" section and I'd like to see it take on face of popular questions (most ask) with answers.. perhaps directly linked in to threads from the archives. My personal conviction is that it become a prowerful cayatlist for thinking and a bank of knowledge. There is a fair amount of information that comes out in the forum that will never show up in books nor is able to be represented with calculations. The so called "black art" of engineering and engineering related diciplines. This information must be either learned by much trial and error or passed along by "masters" to those learning the processes. Such information is currently being lost by the gigibite as our "masters" pass on. Such a forum as we are discussing (includding the current ones) would be a media to archive, catalog, pass along, and thus save these valuable "bits" resources. Another area (triggered by the brain craze above) that we may not be quite ready for yet, would be a section for engineering tricks and shortcuts. I see this somewhat like the popular sections in trade rags where readers send in simple little ideas that save time and efforts. These often trigger some powerful inventions and concepts. I'm sure many inventors pour over those sections of magazines the moment they hit the stand with hopes of being the first to capitalize on an idea seen there or to use it as fuel to feed their ideas creativity.

yeah, ... such a wealth of data, if we could just figure out a good handle.. what greater asset it would be. for example (my example): I'm working on a project in which I need to figure out the HP requirement for a motor to drive a small hydraulic pump that will drive two parallel hydraulic motors. The pump will be running around 1000 RPM and the motors running around 20 RPM (this is a displacement ratio function) providing a tremdous leverage advantage. The mass to move is 4000 lbs at what comes out to be around 40 feet per minute. ... when I searched for horse power calculators I got (I forget what but it wasn't much help).... great calculators but not to my application and I figure there are others in the system that I didn't find. a quandry.. .. I'll be thinking hard on it! toward suggestions. ... there is no model out there to use for a pattern... this is new ground.. let me stur my brains a bit. thanx... later.. The worst suggestion of your lifetime may be the catalyst to the grandest idea of the century, never let suggestions go unsaid nor fail to listen to them.

just tossing it out there... thinking of a tree... let me explain... user: Animal.... system: tail or no tail? user: Tail...... system: hoofs or toes? user: Toes...... system: quad or bipod? user: Bipod..... system: here are my best to choose from The worst suggestion of your lifetime may be the catalyst to the grandest idea of the century, never let suggestions go unsaid nor fail to listen to them.
