Hi there,

I am basically using MapleSim to obtain the equations of motion for mechanical systems and copy

pasting them into a separate Maple document and solvng them numerically. I could work with simple pendulum

and a two link manipulator. But in the case of a four bar mechansism since the system is a closed chain the

number of unknowns ended up being more than the number of equations. In this case, the joint reaction forces

came into play as unknowns. I know MapleSim intelligently does index reduction and solves these equations. But

hello friends

please help me.

I already have an spline equation in maple13. I want use this equation as a signal block mathematical funtion. But maplesim only have standard funtion blocks in this pallet :

Signal Block\Mathematical\Functions

 

Thanks

 

 

I want to make my Maple12-procedure faster by creating two threads instead of two:

I have an Nx3 Matrix A and each row looks like [integer,integer,*]. Matrix A acts like a function of two variables in the sense that the ordered pairs that you get be selecting the first two entries of each row are all distinct.

I would like a slick way to convert A to a Matrix B for which B[i,j]=* where * is the third entry in the unique row of A that looks like [i,j,*]. We can insert 0 for "blanks."

For example, if

A:=Matrix([[1,3,a],[1,4,d],[1,1,b],[3,3,c],[3,4,a]]) 

1 3 a
1 4 d
1 1 b

Hi there,

My name is Sasi Bhushan Beera. I am Graduate Student in Mechancal engineering at UB.

I have been working on dynamics of mechanical systems for my research. What I intended to do

was to obtain equations of motion using MapleSim and copy paste them in a seperate document

folder and solve them numerically. Considering the case of a Simple pendulum, I was successful

in doing all this but I had problems with animation of the pendulum.I need some help with the animation

hye.. iam zarith.. i want to ask u whether there are solution to this differentiation of delta f over delta f. please

Hi!

Hi all, Is there anyway to solve this differential equation in maple? (diff(x^2, x))*(diff(w(x), x))/x^2 = 480*(Int(0.2538690379e-2*l^2/(exp(4.651162791*10^6*l^2+9.302325581*10^6*w(x)-1.600000000*10^9)+1), l = 0. .. infinity)); Initial conditions: w(0) at 0 and w'(0)=0. Thanks

How do I generate a list of equations with Maple procedure. My problem is this, I have a Pile embedded in the soil. L is the length of the pile, it is divided into t equal segments, thus there are t + 1 points along the length of the pile. The point 0 is at the tip, and point t is at the ground surface. Y[m] is the general deflection equation at any point m along the pile. My goal is to generate each equation for each points along the pile, such that I can invoke Maple solve function to solve the problem. Below is my input into Maple.

From format->autoexecute , I wanted to press "clear" but accidentally pressed "clear all" ... now all 200 of my autoexecuted functions (which were very carefully placed and is not easy to remember which ones they were!) have been removed and pressing edit->undo does NOTHING!

I'm so lucky that I save my maple worksheets every time I make big changes (so I have maybe 36 versions of this worksheet!) .... but should maple not be able to "undo" somehting THAT simple!

 

 

The question is:

 If the stock price today is 100 and the stock has a anual volatility of 12% what is the probability of that stock

being within a price range of [130 - 140] in 5 months time ?
 

 

Answer:

I tried the following do loop

 for k from 1 to 4 do

s:=0

xmp:=lstt[indlax[k]]

s:=ym(x)+s

end do

 

 

where xmp is getting a numeric value from list "lstt" for each k

ym(x) is a piecewise function containing unknowns x and xmp,

what I would like to get is ym(x) for each k, and sum them up

 

Thanks,

by the way, is there a nice way to copy the output (those arrays) and paste them into something like notepad? I'm really having a hard time (notepad just treats it as an image or something like that).

Hello, I've been trying for weeks to solve a system writen in its matrix form like: M*y(t)'' + C*y(t)' + K*y(t) = F(t) My system can have like 300 dof. If I generate all de equations and I use the dsolve/numeric command, it works but not all the time. I think that there is a problem with the Heaviside function that I have in some coefficients of my matrix. I've been reading in forums that it's better to have a first order system to solve complex problems. For that we can create a procedure as explained in the dsolve/numeric/IVP help.
