mechanical exercises applied to machines

[Fulvio Romano]

in any case my question is simple. After setting four closing equations, I get a system of eight scaling equations. What do I do? Do I have to fix this? What does matlab have to do with it?
Thank you!

Can you get the reciprocal position of the links according to the cylinder length?

from this, then if it breaks up matlab.

 

[snaroz]

in the system that I got there are 24 unknowns, including the length of the hydraulic cylinders and the angles formed by the vectors compared to the x axis is normal?
Thank you!

If I'm not wrong I should write four closing equations, then solve a "system" of eight equations or wrong? What would there be to implement in matlab?
Thank you!

Hello, snaroz. I'm also following the pennestry course. from what I understand matlab should come back useful when we proceed with the iterative phase of the resolution through the method of polar diagrams (not if you remember the final formula {x} = {x0} – [ J ]-1{f(x0)} ).

Where are you? ? ?

 

[Fulvio Romano]

Unfortunately in these days I have very little time... start posting an interesting introduction to matlab.. .

 

[marcolenzio]

I wanted to ask you a question... how did you face the 4 independent circuits?
classic churus equations or with newton r.? the problem arises because we do not even have a data available from which to leave thanks .... .

In theory we should import the image in autocad and draw over it the schematized members and couples. from this schematization we should calculate with a special command of autocad the degrees between the various members and use them as values of first attempt to insert in the iteration.

 

[marcolenzio]

So once we do this, should we implement with newton r. in matalb? ? ?

 

[marcolenzio]

alive87, if you're a torvergate tomorrow, we could meet in class. to compare the ideas you say?

Hello, but the number of independent circuits isn't 1?

 

[marcolenzio]

to me come 15 cinema pairs and 12 members.... if you use the formula of independent circuits i.e. (j-l)+1=4. do not return this? ? ?

 

[tortellino]

Excuse me. .
pennestrì is the worthy heir of blessed (and that's enough to qualify) but from here to imagine that he claims that for a single table one should prepare the numerical calculation exam and/or remedy a calculation program, there is running.

 

[tortellino]

Are you an oracle or part of the secret services? :biggrin:

ahahaha
Noooo.
I did the argument in good time and showed me the exercise in question.
In a way I saw him born:

 

[snaroz]

to me are 6 members and 6 cinema pairs, as I said in previous posts

I agree with Tuesday, even to me are 12 members, 15 pairs and consequently 4 independent circuits.

Sorry, guys, about autocad someone of you knows what raster images are and how do you care?
