Thanks for all the replies everyone. The cow example was especially helpful.

Can someone explain in really simple terms the difference between ASD and LRFD? ASD seems easier but is it going away? I was reading through the new AISC Steel Construction Manual about the two methodologies and, aside from the different load combinations, was having a hard time seeing a clear...

My 35s keys have the typical soft click you expect from HP. If your 0 key or clear key is making a noticably different sound than the other keys, I'd say there could be a problem, especially since they're right next to each other. Loose keys are also a bad sign. Sounds like a legitimate...

Just got my 35s over the weekend. Two words: GET ONE! Pictures don't do the 35s justice; it's really a good looking calculator. The plastic case is black, and the aluminum cover plate is a very dark brown, almost black. The lower half of the key pad, the enter and backspace keys and are black...

I just ordered a 35s from Amazon over the weekend. Being the cheapskate that I am, I stuck with the free shipping, so there's really no telling when it will show up. I'm interested to see how it stacks up against my 33. In any case it's nice to see that HP appears to be listening to what people...

The nozzles are at pretty steep angles. At first glance, it appears that the developed opening could be double the nozzle diameter. The latest plan is to treat the nozzles as if they are perpendicular to the vessel and use the developed opening as the nozzle diameter. Is this a common problem...

First off, I'm new to the forum and pressure vessel design. I'm helping out on a vessel that has several nozzles on a cylindrical shell that are at compound angles to the vessel, i.e., they are not perpendicular to the vessel as is typically shown in WRC-107 sketches. The customer supplied...
