Does anyone know of a more simple equation to derive the max moment of a simply supported beam. I have 12 equally spaced loads with the first and last being spaced further from the support than the typical spacing. Exterior loads are different from the interior. Heres some pictures of what im working with. The BMD diagram is my check for the moment of the HL93 Inv Loads. I've done this before when only working with a couple concentrated loads but the formula would be to long for this. Would also like to be able to check the moment at any location along the beam    

I wanted to install Mathcad Prime 4 to my new pc.The license manager accepted my product key but I can't chose the product for the license.

I just got a hold of MCP10 and started playing around with the new Advanced Controls. It appears that these controls are using Microsoft's Jscript version 5.8.  This is semi-equivalent to JavaScript/ES3 which is 11 versions behind the current version.  There are a lot of missing features that are commonly used in modern JavaScript, and I would like to at least upgrade to ES6. I was able to add the methods for working with JSON using this code in the TextBoxEvent_Start function to download and execute the json3 polyfill...   var xhr = new ActiveXObject("Msxml2.XMLHTTP"); xhr.onreadystatechange = function(){ if(xhr.readystate == 4){ eval(xhr.responseText) } } xhr.open("GET", "https://cdnjs.cloudflare.com/ajax/libs/json3/3.3.2/json3.min.js"); xhr.send();   Tangent: Yes, I know eval() is evil, and this opens me up to security risks if cloudflare ever starts sending me something malicious instead of the json3 polyfill.  If anyone h

I can't seem to get TextAlign to work to centre the text in the textbox.  Any suggestions?  Also for vertical alignment please 🙂 Is there any documentation with all the implemented properties for all the new control objects?  Thanks,

I made a couple simple functions that I would like to share that helps with debugging of long Mathcad Prime (circa v9)  programs.  (file attached) I was making a VERY LONG convoluted program that called several sub-functions (in order to split it up).  But it still had bugs by the time it was fully grown (don't we all;). I made this function so that I could locate the errors before it happened.  It is basically a logger that lets the program continue.  It is better than a "return" statement in a few ways: Since there is no 'remarks' statement in programing, this can also be a substitute—they do not need to be removed (except for speeding up long iteration functions).You do not have to delete the "debug" functions in order to keep the program running and running to a proper conclusion whereas "return" statement must be added/removed every time it is needed."debug" functions do not screw up the output if it is in a sub-functionYou can display the d

Hi there, I'm wondering what does the (i) represent in mathcad?  

Hello everyone,i want to program this in Mathcad. Could someone help me with this? 

I have just bought the mathcad student edition and never recieved the product code.

My laptop that had downloaded MATHCAD has broken and im trying to move my license over to my main PC, is there a way to do this without creating a new account?

Instead of simply stating the equation with its result how can I should break it down to show the specific values assigned to the variables and how they contribute to the final result. for example if I have p:=10 q:=20 I want to show r:= p+q=10+20=30 is this something i can do?

Hi everyone,I want to use two different vectors in one equation ...what should be the iterator f ,q and dz  I used length function but it gives me strange results    

Hello,My co-worker has installed a newer version of MathCAD, and I am now unable to access files that she has saved. I would like to update my version so it is compatible (but continue using MathCAD Express).I have tried using the website to request a new installer, twice in the last two days, but the promised email has never arrived (and yes I have checked my junk folder).Are you able to help me out?Cheers, Daniel

I just had a look at unanswered posts, and this was at the top of my list:   https://community.ptc.com/t5/Mathcad/Prime-9-Chart-Components-Can-Become-Corrupt/td-p/956950   I have been struggling through a file I created originally in Prime 9 that has 3 chart components. The first is a simple chart component with absolutely no modifications made to it, containing 24 curves. The second chart has 6 curves with customized legend, line styles, title, etc. The 3rd chart has 10 curves and all elements of the chart are customized heavily (chart title, legend, trace names, line type/color/thickness, axes names and tick mark font sizing on all elements, etc.). This 3rd chart continues to become corrupt after saving it - of course this is the one that needs to be published! NOTE - Prime 10 seems to be "behaving" so far - hopefully this has been addressed in this latest version. Stay on the lookout for this issue with your chart components using Prime 9!   I thought I'd play with Ch

All, I recently bought MathCAD 10.00 Prime Student Edition and was unaware that once I logged into a certain machine with the license that it would lock in with that specific machine and I would be unable to log in on any other machine. I initially synced up a machine that I do not have consistent access to and I would like to move, or reset, or whatever needs to be done, to have the license that I purchased be activated/synced with the specific machine that I want. Was wondering if anyone could help. Best, - VG

Just one question about ( min function) why it works only with scalars ... whenever I want to use it with vectors or matrics  it doesn't work ... How to overcome this ? Should I always use programming ? For example the following program : in each (qc;gem;cor ) I have 3 matrics each one has ten values.... what I need is to write a program that will compare the both variables and choose the minimum value of each one ( compare the first raw with the first raw  and chooses the min ...and so on  ) ...and the result should be also one matric with ten values. However, it chooses only the minimum value of each matrics  

My students and I use Mathcad to solve problems of dynamics. My students this year (prime 10.0.0.0) come sometimes across an unknown error when using a solve block. The error mentions "bad solve block"; refer also to the screenshot. I have never come across it before and I have no clue what the reason could be for this error. After retyping the equtions and the "find" command, the solve block executes correctly. But I don't see a difference between the original solve block and the one after retyping it. So it stays a mistery why one time it executes and the other time it doesn't. 

Hello I am working on my bachelors project. I have made a function that calculate the heat recovery in a heat exchanger with a faze change (condensation). The function calculates the potential heat recovery based on the temperature that comes out of the heat exchangers hot side. The function works fine but i can not get it to solve the function, so i can calculate the temperature based on the heat energy. Does anyone know how to solve this or the reason for the error?  

I wrote a program to correct the value of q. I wanted to choose always the minimum value and I put the maximum limit to be 15 MPa , I don't know why it is not working . Do you know how to solve this problem?Thanks

I have  R which contains 27 matrics all of them have the same corresponnding depth ( ztips). I want to draw all of the matrics in one plot instead of having 27 plots. I tried the one Mr. Werner suggested before. However, it doesn't work here. I guess the mistake is that ztips and R are different types. The sheet is too long and I can't just substract R because it is the final result of all the above calculation. Sorry for this trouble Page 27 Prime 9 

HiIn Prime 10, is it possible to impose a domain of definition of variables?in a geometric calculation, I do not have enough constraints, and it is difficult to have a unique solution. Is it possible to specify the domain of definition of the variables in order to converge ?Thanks

I have trouble with different versions on my school computers and on my own laptop. I myself have MathCad version 10.0 (free verion) and my school computers has 7.0. Now I can't open files on the older version that I have edited on my own laptop. Is there a way to download older versions of MathCad. I tried it from MathCad Express Free Download but there was no option to select older versions of mathcad to be downloaded.Thank you in advance!

When trying to add product code to a new machine i am told i have reached max license. I found Link to open a ticket. When i try to open a case i get nothing after entering the product code I purchased the code from my commerce any help would be great. or a direct phone number Thanks

The product is for educational use, I am a 4th year Mechanical Engineering student. It would be nice to have the license for one more month.

Last time we wrote this function to classify soil layers. I need to show that in the plot can that be possible in mathcad ?. I need to connect the table with the plot . so it draws horizontal marker whenever the layer changes. or change colors ..any kind of change to make it possible for the reader to understand it changes layer typeLike (y ) will be both z and ztop to draw the plot . z is the depth ztop the thickness of the layers
