I have a cheat sheet of beam equation, all expressed as functions of variables such as w, P, l, etc. The challenge arises when I apply it to compute load combinations, as the beam equation becomes visually convoluted. A reviewer would only see a series of functions, necessitating them to backtrack through calculations to identify the specific function in use. An alternative is to redefine my input variables (w, P, l, etc.) and directly solve the beam formula without using functions, essentially copying the equation. However, this becomes cumbersome due to the need to clear variables for each subsequent equation. Is there a method to explicitly solve my functions and revert them to the original equation?   

Hi Everyone, Any chance anyone has an idea why I am getting odd units?  I did the exponent by hand below just to check and it comes up with 1 like it should.   Thanks in advance!formula:Exponent check:  Version: PTC Mathcad Prime Express 9.0.0.0

Hello Community, I have the following task to solve and i dont know how to do it. I guess its just possible with programming well maybe someone can help me.In the attached sheet i have a pooling problema optimization.Could anybody help me to find coding to solve pooling problem optimization using Mathcad?Thanks in advance GreetingsCarlosRomero 

Again I need help dealing with symbolic arithmetic in MC14. In the German mathematical school magazine "Alpha", issue 2/1993, I found reference to a strange sentence. In the limit towards 0 it concerns the ratio of the area of a curve segment to the area of a connected tangent triangle. Proving this theorem for special curves whose functional equation is known is not difficult. But the theorem applies to arbitrary, often continuously differentiable, curves. The associated proof in the original work involves a lot of writing work. I would like to understand this using the symbolic calculation in MC14. I have attached a “test file” for this purpose. Unfortunately my calculation fails because of the MC message that terms are becoming too large. Maybe I made mistakes too. But the calculation method is easy to describe. I ask you to check whether MC14 can do the calculations symbolically.Kind regards, Alfred Flaßhaar

Hello! I am struggling a bit with the symbolic representation of some complex problems. Please, take a look at the attached file. How can I properly define complex function on form z=r*e^(i*phi)? Should I write z(r,phi)=r*e^(i*phi)? If I do so, then the symbolic evaluation of complex potentials (Phi and Psi) doesn't get along. Also, I am trying to use Re and Im functions to define the real and Imaginary parts of "z" without any success. The same goes to the conjugate of "z": it should be z*=r*e^(-i*phi).Hopefully somebody can help me out. UPDATE:I did some progress, but still can't define properly function "z" without Mathcad telling that some variable is undefined. Updated sheet is attached. Best regards, Sergey   

Hi,The partner sent me the mathcad 14/15. I try to converter to mathcad 8 prime but failed"This worksheet contains 4 locked collapsed areas. Locked collapsed areas are not supported in the current version of PTC Mathcad. You must unlock or expand areas before conversion."Please support to expand the areas or converter to Mathcad Prime 8 ThanksTuong    

It is the site of the article Игра в кубики или Кривая n-го порядка и m точек Readers can see animations and download Mathcad-sheets in replies PS Sorry - it must be not a question but a blog. But now we have not blogs here!

Hello everyone,I am attempting to perform the optimal transportation problema with simulated annealing, but I cannot do the initial approach correctly.Can anybody shed light on this procedure?CarlosRomero 

Does anyone know how to get Mathcad Prime 6 to return the Date and Time? (I know about the time(z) function, its not what I'm looking for. I want to create a 'timestamp' that I can export into Excel with the associated calculation results)

Hi all, This may be a silly question but I'm just getting started with Mathcad (Prime 9.0) and learning the ropes. In the attached spreadsheet I can't seem to use the solve function to find RB with predefined variables in the equation. If I manually input all the variables into the equation the solve function works but if I leave it as I have it, it does not. Am I doing something wrong or can you just not use pre-defined variables? Thanks,James

Hi, I have some questions about the attached file (questions are highlighted yellow on page 3 & 4). I'm trying to extract columns from my matrices Pz, Px, and My and combine them into new matrices, each with a Pz, Px, and My column, plus zero values for Py, Mx, and Mz. My first question: why do I lose my units when I convert the nested matrices Pz, Px, and My to regular matrices with the method I used? Second question - in order from easy to difficult: How do I create one matrix taking the first column from Pz, Px, and My? How to create three matrices with all columns extracted one by one? How to keep the number of matrices flexible in case columns in Px, Pz, and My are removed or added? I'd really like to understand how to do this for future projects as well. Below an image from Excel on what I'm trying to achieve.Thank you!   

Hello, some time ago I downloaded a test version of Mathcad Prime 7.0, which then after 30 days got downgraded to the free Express version. Since then I had to reinstall my operating system, and now would like to install Mathcad Express once again. However, when using the installation file I saved, I only have the option to install the 30-day test version of Mathcad, which I'm unable to do, because the account I use already used its 30-day trial version tied to it. Is there a way to skip this test version and instead simply install the Express version right away?

I have a stiffness matrix where units within columns and rows are inconsistent. I tried to inverse the matrix but it said " The matrix element units are not compatible with this operation". How can I fix this? If possible. Or I just did this wrong. ps: I this question  a few years ago. The very same question. However, the solution is no longer working. Thank you for any inputs!   

HiWhat is the difference between unit  "ton" and "tonne" ?

HiI am using Mathcad 9.0. I want to find the current I1 and put the value into the second equation so that I can represent the equation in I=U/Z from. But I can do it manually and not in Mathcad. I have attached my mathcad file as well as the picture, how I want to express my model.Please provide your valuable time!Regards,Waqas        

Hi, I'm currently having programming issues with converted mcxd files See attached screenshot. It's not reading PRN correctly. I have the file installed and using the read data file it finds the prn file it just won't populate the data. See attached screenshot.Any info would be greatly appreciated. The university used to use mathcad 14 and i believe when converting the file the si units are not populating either.Thanks,Josh             

Hi,I am trying to solve the following problem. I am new to pwrfit function. This is the first time trying to solve such a problem.1. Select a power fit in Mathcad to fit this data and model the metabolism rate as a function of the mass of the animal. Notice that pwrfit(vx, vy, vg) returns a vector containing the coefficients for a power curve of the form y(x)= axb+c that best approximates the data in vx and vy using guess values in vg.2. Determine the R2 value for this fit.3. Considering the fit is good, use the equation to predict the metabolism rate of a 500-kg manatee.  

Hello,On page 8 of the attached sheet, I am trying to build Mohr's circle. I dont know why the Ixymax, Ixymin,... on the plot are showing  in red boxes. Thanks,Sam  

Hi,I'm having problems with using MathCAD to extract the time at which the maximum value of a function happens. I've attached a file with the example. In the attached file, after some initial setup of parameters etc on page 1, on page two I define 2 ODEs in a solve block and solve them with ODESOLVE. This seems to work, and I have plotted the outputs in several graphs. They look as I expect. At some time I get a single peak produced on the graph of f(t). I want Mathcad to tell me at what t this peak happens. I've tried using Maximize, and this gives me incorrect answers for t. I've then tried differentiating f(t) and attempting to find the root that corresponds to the peak of f(t). This works for some sets of parameters and I thought I'd cracked it. But then I change one of the parameters slightly and root stops working, giving me the error message "The ODE solution is calculated over a limited range. Choose a value within this range or expand the range".&
