Mathcad

This worksheet gives the design principles of powerful electromagnet using Mathcad Prime 2.0. This is a water-cooled electromagnet using Hollow Copper Wire. The design may be used for other applications, like motors or transformers.The design combines both electrical and thermal analysis.

I want to express additional y axis.it means that y axis exist two.Is it possible?

I want to find max value about omega when v is variable.I make solve block and I retrict each range.But I can't get omega max with variable v. In other words, I want to find max location about curves.

Hello. I tried to write implement a Gauss-Seidel Method, but got an error. I initialised all variables and wrote all the programming, which seems to be alright, but when I am trying to assign an element of previously initialised vector to a variable, it throws a "This value must be a vector" error. I have no idea why this is like that, I googled the manual about matrices and vectors and it says that Mathcad must recognise 3x1 matrices as column vectors.Moreover, the same code works in Mathcad 15 flawlessly (I have no possibility of using a code convertor included in Mathcad Prime).Any suggestions?

I'm trying to solve an equation & find 'natural frequency' i.e. Wn. I'm using 'angle criterion' formua:S = -0.1483 +/- 0.2143The only way I can find to enter the '+/-' symbol into a worksheet is to drag from; Help>Quicksheets>Extra Math Symbols. But when I attempt to enter the '0.2143' on the right hand side of the '+/-' it interprets the point (.) & puts the 2143 as a subscipt. Is what I'm trying to do possible in Mathcad? If so, how?

Hello all,I am trying to create a function that gives Vforward for a diode as a function of Iforward. Start with a log fit based on a series of data points taken from a datasheet which gives three coefficients to build the function.The function works fine if i keep eveything unitless, however I would very much prefer if the function takes current (A) and returns voltage (V)Any suggestions on how to modifiy the coefficients to achieve this?Thanks,David

After producing a Mathcad 15 plot on a Windows 8 computer, what is the best way to save a high-resolution (ideally 600 x 600) image of the plot on a PowerPoint 2007 slide?

I dont know what I do wrong:(Please look at this in xmcd

how can i get T_2_10k=2360 at the end as a result

SUBJECT: Mathcad version 15.0 (M010 [MC15_M010_20110622])Dear Community,I have a problem with the subject version and build of Mathcad.When pressing the keyboard button that should be the equal sign (=) I get the define variable sign (:=).Even when using the pop up (Evaluation Toolbar) and selecting the equals button on screen the same define variable symbol appears.Selecting the define variable icon does not make the equals sign appear.Any help would be much appreciated.Very best regards,Graeme Y

Welcome everybody, that is my first message here. I just want to know how to define other margins in Mathcad Prime 3.0 ? There are 3 types (narrow, wide and standard) but I need to change them somehow. Can I or it isn't possible?

Does anybody know if this error has been corrected in subsequent versions? Mathcad v14 does not calculate sin(180 deg) or cos(90 deg) as 0. There is a value out to ~16 decimal places, which would not normally be an issue, but I have a 0/0 division calculation that returns an error because of this. Using radians rather than degrees does not change the value calculated. I have created a kludge workaround, but I shouldn't have to. Is there a program fix for this? And does PTC know?

hi, I have a problem. I thought my solve block is not working properly.I posted two pictureI used "if"( red block) to find "a" in first picture.And then I used "a2 equation" to find "a" in second picture.the results are same between two pictures.So I can't be confidence about "my solve block" so Could you check why the results are same?<First picure><Second>

There was a useful collection of worksheets available until recently with a wide selection of topics in engineering: Civil, Electrical, thermodynamics, physics and mathematics, but suddenly it is no longer available. Withdrawing a library with the perception of profit making is the short-term narrow mindness of salesman instead of fostering the use of Mathcad for the long term which is what Mathworks has been sucessfully doing with its well established product Matlab.

I am developing a worksheet that performs a series of simple mathematical operations on an array of data. Sometimes there will be missing data, so I am using NaN for those cases. Most of these operations work just fine, returning NaN for any result based on NaN as an input. However, my worksheet tells me that asin(NaN) = 0, which I did not expect.So, I decided to try NaN with more functions. Most behaved as expected, but several did not, as shown in the attached worksheet. Some are obvious bugs (e.g. asin, acos, log, etc.), but other may just be inconsistent handling of incorrect data (compare gcd and mod).Please look this over and give me your opinions as well as provide other examples that I did not test. PTC, please look this over and incorporate the needed fixes for the next release. Thanks.

Hello everyone As I can extract values from different columns of a matrix and get the total sum. Attached is a sample sheet with what I do.Thanks in advance

Hi,I have tried to do some fixed-step equation solving for power converters, and I have encountered a very weird phenomenon : a unit assigned to "0" without being asked. here is a file that reproduces the problem. The "physical" model is a boundary-mode buck converter. The switch is on (PWM=1) for a fixed duration (ton), then off (PWM=0) until the current in the inductor reaches 0. When the PWM is set to 1, no problem, but when it is set to 0, Mathcad strangely sets it to 0s. If I specify a unit, this units "overrides" the s. If a unit is set to the "1" condition, it applies automatically to the "0" condition too (???). The only way I have found to get rid of this is to do PWM:=PWM/SIUnitsOf(PWM), but it would be much better if it didn't force some unwanted unit in the first place. Any idea where that comes from, and how to prevent that from happening ?Thanks

I need to convert mathcad 15 results having mm to fractions inches using scriptable objects)

I do not usually stand on a moving escalator and go through it.I want to pass the maximum number of steps. Up or Down!What is the speed (steps per second) should I go?One symbolic and numeric solution I need (from my students too) PSThe largest escalator in the world is located in Moscow, at the metro station "Victory Park". Its length is 126 meters and height of 63.4 m.Escalator speed - 45 meters per minuteThe width of the steps of the escalator - 0.4 m
