HP 48GX or 49G+RPN? Message #1 Posted by Dan on 6 Dec 2000, 10:59 a.m. I'm thinking about purchasing a new HP and don't know if the 49G+RPN has any advantage over the 48GX. I'm a structural engineer and use my HP 28S everyday. The casing is starting to split around the batter-holder and if it splits all the way, there will be no way to keep my batteries in the calculator. This is the second time it has happened and the first was covered under warranty. Any suggestions are appreciated.

Re: HP 48GX or 49G+RPN? Message #2 Posted by Marx Pio on 6 Dec 2000, 1:38 p.m., in response to message #1 by Dan I'm a structural engineer too and if you want a machine to do the job the HP48GX is the choice. I own a HP49G but I really didn't like the keys that are made of rubber, but 49 has 1,5Mb of flash-rom and are faster then 48GX. I used an HP28S for a long time with a program to check bending moments and shears on a multispan beam, and you are right in be dissapointed with the battery holder. I have an HP 42S with the same routine for beams and an routine for bending moments and reactions on a isolated slab by the Marcus process. And day by day job, I use a 16 year HP 15C. In fact, PC Structural Analysis softwares will help you be more productive, and the small routines in HP machines will lend a hand on-site checking. Pio

programs Message #3 Posted by Dan on 6 Dec 2000, 2:44 p.m., in response to message #2 by Marx Pio What is PC Structural Analysis software? Also, do you know of an internet site that would list programs for HP calculators? If it's not too much trouble, could you send me the program you have for calculating moments and shears on a multispan beam, and/or the routine for the isolated slab? Thanks, Dan
