Algodoo

Yes, they both work on the same principle. I was trying to make a lower profile and simpler version of the fractal vise. Also, the pink, green, and yellow intermediate parts could each have one center ball and three sockets on a common circle so you would end up with (27) blue pads. The fractal vise adjusts in 2D whereas this vice could adjust in 3D.

Would a 1/2 fractal vise against a flat steel jaw be precise and rigid enough for that type of work? If so, then would a spherical (as opposed to cylindrical elements)1/2 fractal vise against a flat steel jaw work?

You may mean "Kurt" vise. A perfectly rigid and precise vise may not work as well as you would expect unless you are clamping parts that have two perfectly parallel faces. A vise where the linear guide angular play is slightly larger than the angle tolerance between the two almost parallel faces of the typical part would work better. Ideally, the moving jaw would conform to the part and provide high uniform pressure in the direction perpendicular to the face of the fixed jaw while providing high friction and high shear resistance in the direction parallel to the face of the fixed jaw. That's what I was attempting to accomplish with the whiffletree vise jaw. An improvement to the whiffletree vise jaw would be to have the elements return to their nominal position when unloaded.

Thanks. Good suggestion, I may use it.

could do
rotation = math.atan2(scene.my.vel(1), scene.my.vel(0))
since
math.atan2(y,x) returns the angle [-pi,+pi] of the vector [x,y]

I'm seeing red.

You might be interested in Array Functions.

Thanks. Good work on this scene. I like the overall layout, straightforward explanations, extensive code comments, ability to handle multi-dimensional arrays, and circular indexing.

You may want to adjust the unilateral phase detractors.

I use Notepad++ for editing. I googled "sublime text" and see that it is similar to Notepad++ but is more popular than Notepad++.

You probably know this, but for people who don't, you can save Algodoo objects and paste them into a text editor. You can also save an Algodoo scene as a .phn file and then open it in a text editor.

Thanks Xray. Now it's a feature (See note #5).

This is an exact copy of Animated Alphabet. I guess your way is to steal other people's work and put your name on it. I'll assume that all your other scenes are also copies of other peoples work.

I don't understand why the engine mass is changed to 2450 kg while moving. It looks like you set the density to 800 kg/m^2 instead of setting the mass to 800 kg.

Looking good.

Nice work. Planetary.

Thanks. Done. Code is in the button _onMouseDown and _onMouseUp routine.

Very creative.

Nice work. I suspect that the younger the child, the better this scene works.

Nice work.

Nice work so far. I made whole ratel invisible and without borders then added fur from Animal skins Seamless Texture #4972 to all the polygons. I then made the toenails, nose and eye black and the teeth white. He's looking pretty good now.

It looks like you spent a lot of time making this scene but not much time describing how it works. You mention "Reach destination" but don't describe where the destination is. You show "Click on Plane To Move" but don't mention whether there is any skill involved or if playing the game is totally random. The plane button spins and does something but the real plane direction has no relation to the plane button direction. Eventually a user will figure out how the scene works and maybe that's your intention, but I suspect many users are lazy and may give up before figuring out how the game works. This scene is good but I don't know how many users will take the time to appreciate it.

Thanks.

Your car breaks the laws of physics. The car gets accelerated to a velocity of 16 m/s before hitting the platform. That limits the car maximum increase in height to 13 meters. There's some funny business going on with springs.

Looking good. Parachute in title.

Added as a response to this scene. OK to copy or choose your own favorite fur. I will delete the response scene if you add fur to your scene or if you request I remove the response scene.

Thanks.

Looks good but something is not quite right. The ball is not the mass you set it to be and the ball looses 60% of its total energy going thru the loop.

It's a beautiful thing. Very well done.

I see a way to win without cheating. The platform wheels extend 0.0099 above the platform. If you make your car wheelbase the same as the platform wheelbase then you can use the platform wheels to transfer energy into the car. The stored energy from the platform wheels plus stored energy from the kinetic energy conversion will propel the car past all the previous entries.

Not my scene. See Chess Match Player for my chess scene. Your comments above also apply to my scene. I don't care. Coding for all moves and possibilities is too much effort. I assume the users know how to play chess. I promote only to a queen because that is what people will choose most often.

Q: Do you know a good source of information about compliant fasteners?
A: Not yet. I searched but kept on coming up with info on complying with screw thread standards. I came up with some info when looking for "screw thread load distribution". There was some info here, near the bottom of the page. The distributions shown assume perfectly matched lead between screw and nut. Slight differences in lead will cause big differences in load distribution.

Possibly the best looking plane in Algobox. Nice work.
