revist of the online machining calculator site

A follow up for people interested in building offset keys.

Ronnie Shultz (the original poster on this topic) and I
collaborated via email and I was able to build a program
that met Ronnie's needs.

The program (OFFKEY) is available free (as are all my programs)
on my webpage:

Guys who are using PC's should remember that the calculator in Windows appears to be a simple four function calculator, but it is also a fairly decent scientific calculator.

It would be nice to have a calculator for the strength of steel beams. Such as how much weight can you safely put in the center of a 4" I beam 6 feet long or 2" squar tubbing. The formulas are in the Machinery's Handbook, but they are a little long for an old guy with more gray hair than gray mater. I think the input should be such as: Type of beam ? Strength of steel 60,000? Size of beam? Length of beam? = XX pounds safe load. You then need to put lots of disclaimers about still not standing under it, if anything or anyone may be at risk hire an engineer. It would be nice to know that the 6" beam on the press is way more than I need or that the ramp that I build for the trailer really will not hold the tractor before I test it.

Thank you,

Such calculators are already available on the web. Use Google and search
on something like "beam strength calculator". When I did that I got ~6000
hits. The calculator at 'efunda' looks fairly complete.

Personally, in our litigious society, I wouldn't put such a calculator on
my site even if I had written one.
