Yes, they will send you the free version of WM2D on a CD, but I think it took them about a month to get mine to me. By then, I had already downloaded. With a 56 kbps modem it took me over an hour to get it all. With a 28 kpbs modem (does anybody still use them?) one should figure on a download time of about two and a half hours.

re: WM2D
On 7/6/06, I found, in any overbalanced gravity wheel with rotation rate, ω, axle to CG distance d, and CG dip angle φ, the average vertical velocity of its drive weights is downward and given by:
Vaver = -2(√2)πdωcosφ
Vaver = -2(√2)πdωcosφ
re: WM2D
Hey Ken,
I did download the current version (took about an hour and a half I think - not sure, I was watching a movie), but it doesn't work on my 98SE system. That's why I was wondering if version 7 is available anywhere. If they just send me the new one on a CD it prolly won't help much.
Btw, I've had 56k modems for years (this is my 3rd I think?), but it's Southwestern Bell's local phone line that causes the 28k bottleneck.
A month ya say... :/
Cheers, Mac

re: WM2D
Btw if anyone else has problems with WM2D, there's another free 2D program (Silux 2D) here:
http://www.silux.com/software_download.cfm
Just installed it a bit ago and haven't done much with it other than run the samples yet, but at least it works on my system. ;)

re: WM2D
I downloaded silux a few days ago and I've read the manuals. Now I need to figure out how to use it. I doesn't seem to be as user friendly as Working Models. But from looking at the samples run it looks like it might run the models better. Time will tell!

re: WM2D
Well I downloaded Silux and it seems like a pretty good program for a freebie. But as Jim_Mich remarked it does seem a lot less user friendly and probably harder to learn than WM2D.
It took me a couple of months to get reasonably competent with WM2D . I think it would take me a good deal longer to get the hang of Silux and I dont think the program has the capabilities that WM2D has.
WM2D is over 20 megs, while Silux is less than 2 megs. So it seems to me that there is probably a lot that Silux doesn't have.

Jim, W2K is Windows 2000 I believe.

Windows 98SE 4.10.2222 A
AMD XP2400
Nvidia GeForce MX 440SE AGP
512 mb RAM
The XP2400 is clocked down (lol, yes down) to 1800 because it runs so much cooler. Still meets my needs and doesn't have to be cleaned near as often (kind of dusty in the room with my hobby/work table).
Also have a 3Dfx Voodoo 5 PCI video card which can be swapped in the BIOS (along with an AB switch), but I noticed no visible difference between the two on Silux.
Silux is a bit more complicated than I had hoped though. The WM2D CD may be here by the time I get a grip on it. :/
Btw, the Silux downloads are about 6.1 mb total with the additional PDF files, and WM2D is approx 18.5 mb. This could mean more features in one, or better coding in the other (among other things). No idea which is the better program.

re: WM2D
Mick...
Here's some wmb Script (previously provided by Jim_Mich, I think) that will let you instantly create ratchets of various types. Just insert this code into you Script Editor window (after deleting any script already in it) and Run it. You will have to substitute different values into the parameter lines (which I've colored brown) to vary the shape of the ratchet's teeth and which direction toward which they slope.
Perhaps, if you make a ratchet of the right shape and then use a chain of circles that are linked together with rigid rods of the correct length, then you might be able to make a fairly accurate chain and sprocket system. Make sure, of course, that the ratchet and the chain circles are set to Collide so that the circles will get caught between the teeth of the ratchet and force it to turn.
Good luck...

re: WM2D
Mick...
Sorry you are having problems with the ratchet code. I have not used it in a while because my current research does not utilize ratchets, cogs, or pulleys. I think that after you put the code into your Script Editor and Run it, you will get a message telling you that the data is in the Clipboard memory and ready to be pasted. You must then make a polygon figure on the Workspace, left click on it to highlight it, then click Window on the toolbar above, Geometry, and when the Properties window pops up for the part, select Shape and then hit Paste to put the data into it. Then, the part, which might be a crude polygon circle is supposed to snap into the shape of the ratchet with the geometry you selected.
You need to consult Jim_Mich on this one because he has done more work than me with these types of parts. I'm sure he can "walk you through the process". It sound complicated at first, but practice makes perfect.

re: WM2D
No apology needed Ken.(Edit:wrong context...make that concern)
I haven't had time to try the code yet , however I'm glad you posted the additional instructions.
I felt sure there must have been a command in WM2D to achieve the objective and that I was too thick to see it.
I seem to be spending too much time on the software and not enough on the "quest".

Mick

re: WM2D
There are 'pulley' & 'gear' icons that you can use. Failing that, do an advanced search on user name 'Tinhead'. He posted a demo adjustable pulley arrangement about a month ago in Graham's thread IIRC.
P.S. when using the gear icon just click on the 2 objects (cogs) you want the gears to work between. In 'properties' manually adjust the ratio otherwise it will be automatic according to the radius of the 2 circles (cogs) that the gears are attached to.
Note that movement one way will induce movement in the other in the opposite direction, just like the real thing. If you want both parts rotating the same direction place an intermediary idler gear in the assembly but I prefer to use the properties window again & select 'internal' gear (which highlights one cog) & then both turn the same direction.

re: WM2D
Thanks Fletcher
Unfortunately the int gear option is out (1:1 ratio) and I don't want the idler with ext gears.
Tinhead's pulley demo (from beginning of this thread) may be ok...
but as I've only the demo version I can't load/view it....Bummer!
I think I'll try my idea with hardware..
