Any idea of why this error message comes up? The answer should be about 600 in^4. The last yb1 should be yb2.

Those are literal subscripts, aren't they? i.e., Ix.C vs. Ix[C? The gap for an index is larger than the gap for a literal.

Can you upload the sheet?

1.58e8 + 87696568 = 2.45696568e8

That's above the limit for a signed 32-bit integer.

I don't know if that's important for this case, since SMath shouldn't be using signed 32-bit integers for what you show. Unless somewhere internally it's using them for the conversions between in^4 and mm^4.

Does SMath give you any control or visibility about the number types that it's using?

Thanks Mint... that could be the problem... drop the metric to m in lieu of mm... I'll try it.

It doesn't help... It's storing some huge numbers internally for what ever reason... dunno why... I removed all the metric I values... and I get the same message.

As I noted above, the numbers SMath is using, I assume internally, are extremely large. I don't know if it's possible to set a 'switch' of some sort. I couldn't find a 64 bit Windows version. It's a problem that's popped up a couple of times of late. I'll try reinstalling the program... see if that helps.

I would copy everything into another sheet, first.

There's nothing that I see in what you showed that should be problematic. Smath's largest number is around 10^308, so it's unlikely that anything you do in a structural calculation for something on Earth could exceed that.

Thanks IRS... I'll try that first. It is problematic, and only popped up a couple of times of late... never before...

It's very interesting because just assigning the sum to anything screws up, but the sum by itself works fine as 590.279914418849000*'in^4

I broke the value up because it originally worked without the error... treating the total value... as a work around, I'll enter the value of the summation.

Oh, Oh, the number is different... something really strange... It's OK, I changed the beam size to a W16...

Even more perplexing... I'll see if I save it as a different file name and see if it works... bug of some kind. Current rendition... I use yellow boxes for adding data...

Don't know exactly what happened with the sheet; feels like one of those things that Mathcad would occasionally have. Something for the Journal of Irreproducible Results ;-)

There is a transformation of some type with eng-tips... saving it as a different file doesn't work to fix it. I'll have to use the work around and hope it works.
