I having some problem in key-in some equation in mathcad. I had searched in few sources, but still haven’t get proper solution for it.

Hereby I had attached my hand calculation. Please advise me how to key-in that formula/ equation in mathcad.

I hope for your kind co-operation.

Welcome to the forum.

Something like the attached?

I haven't time to type the whole sheet out, so maybe it be prudent to type out what you can and pass a worksheet in the forum.

Thanks mike and vladimir. I will review the handbook.

But i have try the calculation in Mathcad. Could you check it.

And for sure my calculation for derivatives (dMCB/dP1=0 and dMCB/dP2=-x)are wrong, im not sure the correct one.

Thanks a lots

Please, look at this example. I hope, it will help.

Thanks a lot guys..

I think, you need to look in "Mathcad Handbook Roark's Formulas for Stress and Strain".

The new alternative to Roark's, at a massive discount from $10000, is "Wayne's"

Richard, you are a wise man.

I am trying to think of something clever to say..............................nope, got nothing.
