Mathcad

1. I meant to write nC/m^3 as a unit, nanoCoulomb per meter cubic.However mathcad considers it as something else (variable maybe?)All the calculations are correct.What should I do?2. I should put unit meter m on variable r2.But if I do that, the calculation goes wrong.any idea?

I'm trying to output mathcad results as excel or text files so I can imbed them in word, but it seems to me it only allows you to write dimensionless numbers? Is there a betterway to do what I am trying to do?eg I want a word document that says;"In conclusion, the Area is 2 in^2"where the number is calculated by mathcad. (the report is way too complex to do in mathcad alone, I need heading styles, tables of contents, image references, bibliographies etc. etc.)

How do you get horizontal and vertical alignment in Prime? This new grid does not do a very good job.

I try to find forces in this task. The Mathcad 15 sheet is in attach. Are equations in the Given-Find block right?What is the 8-th equation?

I have developed a simulation for GEV distribution by using log likelihood estimate. However, there are some errors on that coding.From that code, I expect every parameter (location, scale, and shape) should be come out in matrices not an integer. Hope someone can help me.Thank you.

   Hello Everyone,   From :          So the question is : Is it possible to create a program function to transform from the Series to a Continued Fraction ?                     Thanks in advance for your time and help.                            Best Regards. 

I have a small programm trying to split a matrix depending on the content in the rows. Now I'm using the folling algorithm:take the row as submatrix on the actual positionstack that on one of the two alternative matrizes depending on a conditionUnfortunately this has a very poor performance both time and memory wise.Assigning the rows via i,j to a new matrix seems to be better. Any ideas why?thanks

Has anyone experienced this before?  The variable I type in comes out as grey, or grey out, and when you try to use it in a formula, it does not work?My worksheet was working fine before, but when I tried to do some "experiementing" with trying to disable certain regions, or certain areas, I get this problem.  I am not sure how to turn it back.I did find a "cure" in creating a completely new file, tested it to see that the variable and formulas show up as solid black and worked.  I then copied the entireccontents of the "grey formula" file to the new one, and the problems seems to be resolved,Not sure what is happening.  Thanks for any feedback so I know how to resolve it later if it shows up again.Dan

Hello,I have a problem with odesolve function in my algorithm in mathcad 15. The puprose is to receive deflection (and deflection curve) of statically determinated beam. The only load is prestressed which generates bending moment. According to Clebsch method I'd like to solve this equation in my case: So I was trying with and without units (You can see it in my file) and I didn't get even one working solution. I'd like to ask You for an advice, because I'm trying to use this function for the first time and I've got no more ideas what should be changed here.Greetings Piotr

Hi,Could anybody help me with the error message in attached worksheet?All the bestPayman

The universal constant R is incorrect in mathcad 15. Is it so for you too?

Hi!I'm trying to solve the deflection of a beam with a constant load along it's length.I have a differential equation of 4th degree with four initial conditions.The moments in the bearings are zero and the deflections too.Now my question is: Why don't i get a solution with "Odesolve" in MP4 although i initialized all four conditions completely?Without Units, it works!The Error Message is: Any help will be appreciatedThank you.Best Regards, Volker

Do you know that we can use in Mathcad Prime? See the picture and try the Prime 3.1 attach! I have created this variable in Mathcad 11 thru Shift-Ctrl-j, opened in Mathcad 15 and convert into Prime. You can copy variable from my sheet, edit its and use in your Mathcad Prime chemical calculation!

I am trying to write a sheet for grad, div, and curl.I am finding that one symbol (rho) is considered as a constant instead of a variable.what should I do to rectify this?

I am doing some cost analysis in the attached sheet. I want to show visually the shapes of the three curves which if I plot each separately is easy to do. However, because the scales are so different I am struggling to find a way to show the shapes of the curves visually on one plot as they appear as straight lines when plotted together. Any tips?Andy

How do we write function to accomodate range of min and max .. in an interation function. Please see attached.I have list of Mw and Mmax values that i want to intergate all at once so that i can later use to plot a  graph. Please help.

Hi again!I'm trying to solve the deflection of a beam with a constant load along it's length.I have a differential equation of 4th degree with four initial conditions.The moments in the bearings are zero and the deflections as well.Now my question is: Why don't i get a solution with "Gdglösen" in MC15 although i initialized four conditions?Error Message: "to few conditions"Any help appreciated!Best regards, Volker...next step will be: Solve the same task in MP4 with Units.

Hi all,I wonder if it is possible to study the relevance of the insertion of a flywheel in the motion chain.I expect to see something by looking the Net Load at the servo motor.My mechanism is a group of an automatic machine: a brushless motor moves a shaft whith two cams that let shift up/down some shafts.Ideally tha angular velocity of the motor (+ reducer) is constant at 840 deg/sec.The equation of the motion is:Mm= motor momentMr= resistant momentJr= inertia momentum reduced to the camshaftIf I add a flywheel on the camshaft I can't see any variation of the Mm.I suppose the reason is that by imposing a constant velocity, the contribute of the Jr (not its derivative) is always zero.For now I don't want to take the resistant moment Mr due to the external forces.Since that I imposed the velocity as a constant, the angular accelration, theta double points, is always zero.If I add a flywheel on the cam-shaft I don't see any variation on the net load (Mm) respect when the flywheel there

Hi guysI am pretty new to Mathcad and hope somebody can help me. I need to know the forces and torques acting on a flat spring I have in my machine. In order to do so I have to solve the 2nd order differential equation and put in the boundary conditions shown below. FMy and MM are not known. In order to solve the equation with odesolve() I have to give values for all constants and it can only solve the problem for two boundary conditions. This is not helpful since I don't know FMy and MM. What would be a smart approach to solve this problem?Regards, Daniel

Doing it with some files that were made available hereOlder Mathcad file conversion What do you think?

In the attached MathCAD 3.1 worksheet and screenshot I'm attempting to determine the left reaction force for three beams of the same length with different loadings. The equation works for one beam but I'd like it to work for all 3 (or more). Each row of the pp matrix gives the 2 loads on each of the 3 beams. The y vector gives the load application point on each beam (it's the same for each beam).My question is, how do I iterate the equation for R over the three beams such that the resultant is a [3x1] vector giving the R (reaction) for each beam?

hello all,i am trying to get my head around integration by substitution.in a simple case of the integrand (x-1)/2 dx  I know the answer is (x^2/4)-(x/2).if I try to do this by substitution, I get a bit lost.ive gone as follows:u= x-1du=1*dxdx=du(u/2)du(u^2)/4(x-1)^2/4(x^2-2x+1)/4obviously this is not correct. Does anyone know what I'm doing wrong?‌
