/diy/ - Do It Yourself

Is this some magic trick or somethin?

>>1446175
Assuming 1 pixel is one foot, you're going to need huge magnets, especial because imitation crab isn't very magnetic

>>1446177
No, I'm just trying to provide an upward force against a rigid object but I am not sure how to do so

Is this even physically possible?

>>1446179
>Assuming 1 pixel is one foot
This is over a very small area and I only need a small force of about 0.15 Newtons

>imitation crab
what's this?

Why cant you tie a rope to it to provide the force

>>1446187
What do you mean tie a rope?

I'm not trying to support anything. I'm just trying to apply a force to a static object

>>1446193
We have no clue wtf you're trying to do.

>>1446175
Just stand underneath it and push it up?

>>1446193
The force is only needed to keep the grey object on the white object above it, correct? To counteract the force of gravity? Or is your image not a side-on diagram? What is the object, what is its mass, what is the surface you are trying to fix it on, and why is the use of gaffa tape not appropriate?

>>1446175
Cut to the chase and explain what you're trying to do.
The answer could be rockets, propellers, magnets, or a stick for all anyone knows.

I'm trying to mimic the tongue pushing against the roof of the mouth, but without a tongue

I just want to know how to do this anon - I'll make a post later explaining what I'm making once I get this working

Yeah OP I can make you a pneumatic tongue.

Don't listen to this guy, he'll sign you up for a dock repair and gouge you on price if you ever let his boots near the ground.

>>1446215
>>1446217
Wow...that's very uncanny

I don't want to make some contraption like that - I'm thinking of the device more designed like that of a retainer

>>1446218
>make you a pneumatic tongue
How would you do this

>>1446219
In any case, every action has an equal and opposite reaction. It is impossible to make something that applies force to the roof of your mouth without it either pushing off another surface (like your teeth or tongue) or accelerating in the opposite direction. To get it to stick magnetically to the roof of your mouth you'd need another magnet or piece of iron above the roof of your mouth that the first piece is attracted to, but then you'll just have the weight of both magnets pulling down on the roof of your mouth, the opposite result to what you're looking for.

Now if you want to push up on the roof of your mouth WITH the help of a chassis on your jaw, then that's certainly possible. Best way to do it would be a plastic frame with a spring-loaded carriage driven into the roof of your mouth, as far as I can see. Not an engineer.

>>1446175
Is this a free body diagram?

>>1446220
like this, assuming through-the-jaw mechanism is acceptable. If you need more PSI go with a hydraulic cylinder instead.

Bully answer

>>1446207
Aww. Fuck you successfull troll. Been pushing my tongue against the roof of my mouth for like 3 minutes now..

>>1446175
Pressurize the chamber or create a vacuum on the other side

>>1448641
damn me too

>>1448641
I'm not trolling though

>>1446175
I figured it out guys!
