Mathcad Prime - Variables

This PTC Mathcad Prime tutorial video shows you how to create variables, including Greek letters and subscripts. It includes the definition operator, evaluation operator, inline evaluation, global definition operator, and even some units.
PTC Mathcad is engineering calculation software that can drive your Creo Parametric models. Its advantages include:
• Natural math notation - no need to learn any special programming language.
• Over 400 built-in functions.
• Document your calculations as you create them.
PTC Mathcad Express is available as a free download from:
www.mathcad.co...
I write for PTC’s Mathcad blog, which can be found here:

Well explained video. How can I define a list variable? for example outside diameter OD = [1, 2, 3] in ?

[@candenizkaya7300]

when I write subscript. it shows it as variable and indicates it in red color. I mean, you wrote v_initial correctly. When I write it, initial is showed as variable(red color) in the sub part. How can I fix it?

[@oceliorios2062]

Congratulations

What if you have one or more unknown variables and you are trying to solve them simulatnously? How do you define a variable that is unknown?

[@CADPLMGuy]

You can either solve a set of simultaneous equations or use a solve block. I think I made a video on that subject for PTC's Mathcad channel.

Hi!
If i define a variable "Mx" as lets say 10kNm on one of the pages in mathcad, on some other page(or maybe even on the same page) I will have Mx also, same name variable but different value. My question is, how does mathcad know, or how do I tell mathcad which Mx to recall to use in some other equation that involves one of the Mx's used. I hope I am clear... Thanks in advance!

[@CADPLMGuy]

Mathcad evaluates your worksheet from top to bottom, left to right. If you redefine a variable to have a different value, below that point in the worksheet if will use the new value.

@@CADPLMGuy great!! Thank you very much!

[@Alen069]

@@CADPLMGuy one more question. i will explain it simply
mathcad will ordinarily do:
a=1 b=2 a+b=3
I want it to sometimes do
a+b=1+2=3.
i hope you understand.
thanks!

[@CADPLMGuy]

Look into Symbolic Evaluation with keywords.

Can you tell me how to write T+1 subscript

[@kinjazz5050]

hi, sir! I wonder how to write X_bar, an average parameter in matcad?

[@CADPLMGuy]

I know what you're talking about - I'm a Six Sigma Yellow Belt. Unfortunately variable names do not support bars. I use a literal subscript to clarify variable names like that.

[@elifkurbanoglu]

I keep getting errors when defining something with this sign :=
What is the reason of this?

Tau is diameter / radius? isnt that .... 2 :)

[@CADPLMGuy]

Tau is circumference divided by radius. If I misspoke, sometimes that happens. It's RUclips.

[@mohitthakur1885]

@@CADPLMGuy isn't that just 2 pi?

[@CADPLMGuy]

I recommend you read "The Tau Manifesto." To us Tauists, it's more than "just" 2 pi. It's a much better way of understanding circles and angles.

c is the speed of light lol

[@CADPLMGuy]

The speed of what?

[@kennyfernandez9168]

Light

[@CADPLMGuy]

Yeah, I screwed up. You got me. I don't know why I messed that up in the recording or why I missed that in the editing. Yes, c is the speed of light, not g, the acceleration due to gravity. If you never make a mistake when recording a video, you're a better person than me.

@@CADPLMGuy a funny mistake can not take away the fact that its a great video man, it just that make me laugh a little bit. 1 more sub!
