Question

How to program in Mathcad

Hello,

I have a variable that will be called "S". I would like to be able to have a program in Mathcad that calculates a range for "S ", so the smallest value will be called Smin, and the largest value is Smax. we need to define another variable "Increment" so that the program will be checking between Smin and Smax by incrementing based on the user input for "Increment".

Each value of satisfactory S that falls between Smin and Smax must satisfy the following conditions :

S/D <= 1.5 where D is the Opening diameter defined by the user.

S/D>1.08

Ratio#1 <=1.0

Ratio #2 <= 1.0

The first S value that satisfy the above conditions will be called Smin, then we increment based on a user input value for the variable "Increment". so the second value for S will be the first value that satisfies the above conditions + increment and so on. we keep iterating until we reach the maximum value for S that satisfies the above conditions and this will be called Smax.

Thanks a lot to all the helpers!

Would you be able to provide a worksheet with the expected results.

Hello Mike,

it is a huge Mathcadsheet. I am using Mathcad14. I am just trying to get how to setup the program since i am not familar with it in Mathcad. but once i see the logic i could probably make little modifications to it. Please see my response to Fred below. Thanks Mike

I can see your point, but you do not have to post the whole worksheet, just an example for users to work with.

Hello!

Please attach a Mathcad worksheet. What version of Mathcad are you using?

We're missing some information. What are Ratio #1 and #2?

Hello Fred,

I am using Mathcad14.

Ratio #1 and Ratio #2 will result from beam checks( Demand/Strength). i have many checks for shear, moment, and (Axial + Bending). I only listed Ratio#1, and Ratio#2 just to give you an idea. Once i get the code, i will modify it to suit my calculations. For now set Ratio #1 and Ratio #2 as variables (user input) just to get the routine. i will customize once i get the idea from you.

Thank you all!
