Bridle Problem

[laserguy]

You pulled that formula out of your head? Hell,...

No not really! If I ever come this far please nominate me for a Nobelprice (maths will do ).
No, I printed your drawing and broke it up into a composition of rectangular triangles... these easily convert into maths .

your inputs...

in our math example you forget that the bridel won't move, due to exact matching vertical forces.

Ok, ******** so it works!
If you give a height (H) of 6 the brideangle becomes 90 degrees
If you give a height (H) of 7 the brideangle becomes 106 degrees
So my 6.61 for 100 degrees brideangle will indeed be correct.

Hello Laserguy,

I would be most interested in your drawings of how you got the formula. Could you post them here on forum?
I am still trying to understand HOW did you deduced that formula.

Kind regards, Grom

edit: I made debugging version of calculator already. You enter v1, v2, h1, h2.
Than you can choose to enter either trim height OR bridle angle. In picture bellow I entered bridle angle - the formula I got from Laserguy, and it works. Below are calculated forces.



Laserguy, I am still eager to learn how you got formula...

Dear Grom,

no problem! I will ask my girlfriend to scan it in... I must warn you: my handwriting is miserable . When she has finished her translationwork I can use her scanner (mine is used as support for my screen...).
So hold on...
Nice piece of work you did on that pocket PC!

can you share this software with us?

Ola Laserguy,

Thanks in advance. I will do my best to read your writings, but it can not be worst than mine...

If you like this program and have pocket pc, you can download rigging software from my website (free). I hope by next week I'll integrate this new feature into my software, ... this picture is working version...

Hey MacGywer,
Sure, go to my web page and download it. But this picture will be available in next days, probably next week...
I can post on this thread when I integrate this formulas into existing version.
or join my site and email me, so I can email you.

Ok Grom,

here is the thumbnail:

And this is the link to the big version:

The block I indicated with "The Key" are the main equations.

Yes I have a pocket PC but it is a HP Ipaq 514 Smartphone (although it runs on Windows Mobile 6).

o, man thanx a milion!

and no, my software is not working on smart phones, only on touch screeners, windows mobile 2003, 5 and 6. And on desktop computers, of course, where it all started.

Best regards!

If you ever come to Slovenia, I'm buying drinks!
