I'm kind of curious if many people still use the programmable features
of their calculators. Most everything that can be programmed into a
calculator can be *programmed* into a MUCH more versatile Excel or
MathCAD Sheet.
Just my 2 cents.

Chuck Dinsmore. For complex simple beams, continuous beams, or very
simple frames, using the card/calculator is easier and faster than using
computer programs, at least the ones I am familiar with (STAAD3 and
SES).
I have programmed many small structural programs that are much more
useful to use on the calculator than to go to a spread sheet. However,
I use spreadsheets for calculating many things that I would not easily
be done on the HP.
I have not use MathCad so I can't comment on it.

I do use the programmable features. Not nearly to the extent as I used
in college and grad school, but the calculator is real handy when you
don't want to have to run back to your computer, open up Excel, fidn the
spreadsheet, enter the data, and then get the answer. It is often a lot
easier to pull out the calculator and just have it do the computations.
Of course, this is only for reasonably simple stuff. The more complex,
I'd rather use a computer. More chances of messing with the input and
seeing what comes out the other end... :)

Rob, I think programmable calculators are good for students and
examination situations where a computer can not be present. I really
like excel and its visual basic programing capabilities, and have
authord many programs. I have tried mathcad and find it very limited,
especially since its database connectivity is very very limited. What
do you think about mathcad?

Generally, I only wrote fairly simple programs--anything more complex
was usually better handled by Excel, Mathematica, C, etc. as you point
out. It is nice to have a programmable calculator though because there
are plenty of times you say to yourself "Surely, somebody has written
a program to do this!" and sure enough, someone has.
So, I think that for most users, the utility of programmable calculators
lies not in the fact that they can program the calc to do what they
want, but rather, they can find somebody else's program and use it.

Most of the programs I use were written by others (Organizer,
Alg48, Diamonds). But I do use some programs I write myself.
When I was an undergrad, I used a number of programs for solving transistor
circuit problems on my 41CV. Today, I'd probably have a similar program
for the 48. I currently use a model rocket altitude simulation program I
wrote last year. The calculator is convenient for these kinds of things
because it only takes a couple of seconds to turn on, and I don't have to be
sitting in front of a computer to use it.
I also like to write little programs to solve various math puzzles or
probability problems, such as Monte Carlo simulations of simple dice
or card games. These are usually programs I will run a few times and
delete. I often do those on my 48, because I can lie on the couch
and watch TV at the same time.
For the number of times I need to write a small program at work, it is
not worth learning a new system. I use something I know instead, even
if it is a bit slower. Thats usually the HP48. When more power is required,
I usually skip the application programs (Excel, Mathematica) and go to
C or C++.

For those folks who don't think that a programmable calculator can't solve
problems when a computer is not near look at the following.
HP-48SX/GX STRUCTURAL ANALYSIS CARD
The Structural Analysis Card for the HP-48SX has been developed
for the practicing structural engineer and students in engineering.
The card contains software that will provide the following:
GENERAL BEAM ANALYSIS
A complete solution for single span or continuous beams with uniformly
distributed loads, linear loads, concentrated loads, or concentrated
moments. The flexibility method solves the continuous beam taking
advantage of the HP-48SX matrix capabilities. Individual spans can be
analyzed for shear, moment, rotation and deflection at any point, or
incremental points. Plot shear, moment, rotation and deflection dia-
grams.
PLANE FRAME ANALYSIS
Plane Frame analysis using the stiffness method. Joint loads, and
member loads may be specified. Member loads may be distributed loads (
uniform and linear ) or concentrated loads being defined as applied in
the local, global, or global projected direction. Output includes
joint displacement, member forces and reactions. Included is the
option for member end releases. Display or print results.
CONCRETE COLUMN ANALYSIS
A powerful Concrete Column/Section program capable of analyzing any
concrete section of arbitrary shape for axial load with one way or two
way bending. The section may include areas of different concrete
strengths or voids. Mild reinforcing and prestressing strands may be
included in the section. Concrete beams, either regular or prestressed
can be analyzed by specifying P=0. Tension may be applied to the
section. The Ultimate Strength Method of analysis is used according to
the 1989 A.C.I.-318 Specifications. This is an excellent all around
concrete section solver.
THE STEEL SOLVER
A Steel Solver program to analyze steel members using the ninth edi-
tion of the A.I.S.C. code for Allowable Stress Design (ASD), load and
& Resistance Factor Design (LRFD). The program will solve for axial
stress, bending stress or combined stresses about the 'X' and 'Y'
axes. Solve and display A.I.S.C. unity equations. An A.I.S.C. data
base of 'W' sections is provided, containing section properties for
291 sections.
The "MENU and SCREEN" interface is used for USER FRIENDLY perform-
ance. The software in this card was developed by Charles I. Dinsmore
P.E. Mr. Dinsmore was involved in the development of the Structural
Design Solutions Book, and the Structural Analysis Pack for the HP-41
Calculator.

Also available are four structural design programs for
the HP-48GX. These four programs were developed for the anticipation of a
second structural card. At present known developers are not pursuing the
market for plug in cards for the HP-48GX and so the second card will
never come to pass.
1. Concrete Beam Design and Analysis using the Ultimate Strength Method.
This program will design rectangular and 'T' shaped concrete beams for
required reinforcing for flexure and shear.
2. Composite beam design. Steel sections with concrete slabs or with
steel deck. Calculates the transformed areas, the stress due to loading
and the required shear transfer.
3. Section Properties of a concrete beam. Calculates the transformed
moments of inertia of rectangular or 'T' shaped concrete sections.
4. Section Properties of arbitrary shape. Will calculate the section
properties of a shape using the coordinate method results being Area, Ix
and Iy and the centroid of the section.
If you are interested in these programs they are available at $50.00 for
all four. You must have the connectivity pack to down load them to the
HP-48 from a floppy disk. Contact

A wonderful idea... now, if we could just interface it with a decent
thermocouple and vibration transducer, you'd have the perfect tool for
someone to go out and troubleshoot rotating equipment - anywhere. Add a
cellular modem connect and it goes into your CMMS. Wow.
Since that kind of equipment (especially in its larger incarnations the
turbine and compressor) is expensive, you can probably sell it for a
heck of a lot, too...
Anyone out there listening? My background is ME, maybe one of you ee
types could build one. If so, don't forget to give Kevin and me credit

I don't. My HP-41cv crapped out after about 10 years and I
replaced it with a much simpler and lower performance HP-32sII.
The little boy in me still wants one of those "plotting calculators"
though.

Rob,
You've certainly started an interesting thread!
I'm fortunate to have access to all three methods mentioned; Excel,
MathCAD, and an HP48G. They all serve a degree of function in programmed
solutions. The HP48, however is unique in that a fairly complex equation
can be plugged in and run with the "Solver" routine with it's dialog-box
style interface. Also handy is the capability of doing iterative
calculations without the constraints of a desktop or even a laptop
computer.
The biggie though; there are folks like Mr. Dinsmore who see a need and
write the code, so applications are widely available for the handheld
world.
Regards,
Glenn
Glenn Capone
Oh, I almost forgot;
With built-in units the HP48 can keep track of units for you during
calculations, and do a very good job of converting units, you can even
combine units and do conversions.
I know this is a piece of cake with MathCAD, but I still haven't figured
out how to make it as portable as a calculator! How about MathCAD for the
HP200LX???

I see the appeal of these programs for a student, but I think I would
rather buy a laptop than attempt to perform these functions on a
calculator.

I have used MathCAD a couple of times a few years ago and find that,
for my needs, Excel works fine.

application is surveying. For construction work (95% of what I do)
lugging a laptop running a CAD application up ladders and scaffolds and
across wet muddy sites isn't an option. A programmable handheld like the
48G is *essential*.
I use TI gear, but that's another story - don't want to start a
brawl!

Okay, okay, I'll bite.
The Psion Siena, complete with a spreadsheet can comfortably fit into
my shirt pocket. With PsiWin software/cable, all Excel/123 spreadsheets
can be converted (while it is being transferred) into Siena's SPR
spreadsheet files.
Psion Siena is 150mmx70mmx18mm (5.9"x2.7"x0.7"), with an 80C86 7Mhz
compatible CPU in it *and* fits in a pocket.
Oh, if your shirt pocket is *much* bigger and you really want a HP,
an HP200LX would do well too. ;-}

I use the HP48 mostly in cases of hopeless long measurement series,
and I wrote some utilities to deal with whole series of numbers placed
in an matrix, specifically to apply a program to the columns of the mx.
and so generate a new one, with results. It's really handy. Krzewas.
Glenn Capone
The main reason that I use it;
If you were asked to review an engineering analysis that was done using
Excel, you would need all of the preliminary stuff, or a print out of the
sheet's equations. In other words, the spreadsheet is not enough.
With MathCAD all of the equations are "live" and complete as they would be
hand written, much easier to have checked.
I find it as easy to use as any spreadsheet, with the added benefit of
being able to readily see all equations used, as well as adding text and
illustrations to a worksheet.
Just my humble opinion.
