Figure Of Eight Motion

[paigetheoracle]

What do you call that motion, where something has a central pivot point and the ends can swing out in a figure of eight movement? Is it called anything in particular?

i can't visualize such a "something"; can you give an illustration?. however, if you were to photograph the sun at the same time every day and put the photographs together, the Sun images form a figure 8 called an analemma .

 

 

figure-8 curves in algebraic geometry are called lemniscates .

Looks like Turtle answered your question, but I'd be interested in why you wanted to know that bit of information if your willing?

Yes. In the UK we suffer from potholes in the road because of the bad weather and they aren't always fixed well, so that they don't last at all or only for a short time. So I thought why not create a hollow underneath, by fixing an excavating tool on the end of a rod, which can swing freely as it is centred in the middle of a tripod, requiring the operator to just move the top of the rod. Then fill the hole with something resilient rather than the tarmac, which water gets in round the edges of, starting the whole cycle again - something like a rubber or plastic plug. It may sound Heath-Robinson and not work but every time I see a problem, I try to find an unused solution: I'm sure this eccentric motion to create a bigger hole within than without is used (or should be) in other spheres of endevour and is similar to keyhole surgery in theory. That's it!

 

I don't know if there is a thread for eccentric ideas in The Water Cooler or even if there's an inventions corner / competition for members but maybe ideas could be thrashed out here and even funded, if considered worthwhile / not too expensive?

i rather imagine the road engineers know what they are doing. i'd suspect budget constraints if the fixes don't last. once potholes get too bad there is no good fix but to repave the whole thing.

 

 

as to your device, try it yourself and i think you'll find it's more trouble than it's worth. that's why they call for a spade for a spade.

Alas in the UK financial constraints mean that resurfacing is avoided until it has to be done and the pothole filling doesn't last (All the rain). As for it being more trouble than it's worth, that's probably what they told Eddison, Marconi, The Wright Brothers and all the other inventors in the world (Try saying that to Quirky, Eddison Nation users et al - I suspect you'd get lynched in no time!) ;)

:doh: you Sir are no Edison. (never minding that Edison publically electrocuted animals with AC current in an effort to discredit Tesla. :weather_storm: )

Butterfly shaped? ...or simply figure 8 shaped.

No, I'm no Edison but I do have a head-son! As for his means of trying to discredit Tesla - thank God I'm not the same! (Tesla was a genius - Edison a mere inventor, a tinkerer*)

 

:blink: Gad, that's me!
