LAguy, Check out underhill's copan software, or his online area calculator. It looks like either one should work for you. Both are available on this link: http://www.underhill.ca/Software/ugl_software.php Best Regards, Michael www.sewellconstruction.com

LAguy, I'm not exactly sure what your question is. Are you trying to determine your closure, or are you trying to balance your traverse? One CANNOT "reduce one's closure error to zero." What one CAN do, is balance the traverse by DISTRIBUTING the closure. There are some fairly easy...

rodbroad, Take a course at your local community college, search amazon.com, try a good used book store, try e-bay, try google, subscribe to magazines such as Point of Beginning, or Professional Surveyor. It sounds like you should think about working for a different firm. Here's a link for...

geophyz, I don't have the model of prism that you mentioned, but I have a couple of dozen different prisms of different types made by different manufacturers. I've tested all of them by forced centering, and I found that they all agreed to within a hundredth of a foot. Sounds odd too me. Best...

pwal2, A Topcon 303 should work fine for what you're doing. Best regards, Michael -Michael www.sewellconstruction.com

mikewi, Use the Topcon. You can shoot angles with it just the same as you always have. You can transition to coordinates when you're ready. It probably won't take you long to learn on your own just by using the owner's manual. Find someone in your area to help you out if you need to. Best...

Paul121, www.softwarebydzign.com has some software for the hp 50g calculator, www.hpcalc.org has a lot of freeware and shareware for the hp 48 series calculators. Doing the calcs by hand or with a cumbersome program is very time consuming. Good software will pay for itself in a hurry. Best...

bashabo, First of all, you'd be surprised at how often you have to extend a prism pole to make a shot. Get a long one, you'll need it. It's also handy to have a 1 foot pole, a good auto level, a set of walkie-talkies, and an assortment of rods, prisms, poles, bipods, and tripods...

Patricia, Thank you for the advice. "Looking for calculations/spreadsheet to determine the stresses in a rotating disc caused by RPM. The application is pump impellers." From: http://www.eng-tips.com/viewthread.cfm?qid=50738 -Michael www.sewellgeneralcontracting.com ALBANY SCHENECTADY TROY NY

iainuts, Exactly what I needed. Thank you soooo much! eromlignod, Not what I was looking for, but maybe even better. It sounds like a "rule of thumb" formula with a built in safety factor. I'm interested in knowing where it comes from. Thank YOU very much, -Michael...

unclesyd, Thank you for the link, but it is one of the 100 bzillion pages that I visited on google during the past 3 days with no equation... -Michael www.sewellgeneralcontracting.com ALBANY SCHENECTADY TROY NY

I am looking for the equations for hoop stress and radial stress in a rotating disk, to calculate the theoretical burst speed. I am not looking for the more complex empirical solutions having to do with fatigue, balance, vibration, temperature, etc... A link would be great. I googled, but...

Please see my posting in Mechanical Engineering - Other Topics. Thank you very much, Michael -Michael www.sewellgeneralcontracting.com ALBANY SCHENECTADY TROY NY

Ah... the formula must be similar to the one used for circumferential stress (hoop stress) in pressure vessels, but with an equation for centripetal acceleration... Would I figure that the entire mass was at the radius of gyration? Am I getting close?... Thank you, -Michael...

This must be a fairly simple equation. I looked through my old physics textbooks from 30 years ago and couldn't find it. I tried to google it, but there is WAY too much information, and NO equations. -Michael www.sewellgeneralcontracting.com ALBANY TROY SCHENECTADY NY

gbpackerman, I don't know if this is the cause of your problem, but IMHO, on any addition to a residence, the bottom of the frost wall footings should be at the same elevation as the bottom of the footings on the existing foundation. I have seen roofing material, lumber scraps, and even tree...

kruzie, Over the long haul, building without an Architect or an Engineer will cost you a lot of extra time and money. I hope that you don't learn this the hard way. Best regards, -Mike www.sewellconstruction.org

basford, fndn is right. Further, ACI membership is inexpensive, and gets you a good discount on ACI publications. It's well worth it IMHO. Best Regards, -Mike www.sewellconstruction.org

The Owner has decided to report the "Engineer". Thank you all very much for taking the time and trouble to provide me with all of the good information and advice. -Mike www.sewellconstruction.org

chicopee, Good guess, but don't forget about rain, the insitu soil that will be deposited on the surface, some oil seepage from the vehicles, and a comfortable factor of safety. Or...ask an articulate truck driver with gray hair (LOL). -Mike www.sewellconstruction.org
