Undergrad If a magnet could switch, could it attract and repel?
That is an amazing concept. I had never thought about it that way... Very interesting, thank you.- zach_wildmind

Undergrad If a magnet could switch, could it attract and repel?
Yes I have seen the video. And yes I do understand it is more than a 2D drawing on MS Paint. I just wanted to know before trying a step forward or if to think of something else. Also you are right some of the polymagnets are quite cheap however the ones I require (twist release) can not be...- zach_wildmind

Undergrad If a magnet could switch, could it attract and repel?
Hello the first image with the letters going ABCD is picture #1 and then BACD is picture #2 for references. Tools: - Normal magnet. Nothing special about them. - And we will say they have some type of system where they do not move sideways. Only up and down and have a difference of 5 cm when...- zach_wildmind

Undergrad Small size Motor to generate this torque
After looking for a servo motor I believed I found exactly what I needed. To be honest I was looking for micro servo motors (I had never heard about these). Basically I didn't need much rpm ( I didn't need it fast) I just needed it to be very very small in length width and height as I need to...- zach_wildmind

Undergrad Small size Motor to generate this torque
Good day everyone. I have two magnets where if I rotate them 20° they disconnect. It has a 0.4 N* m force of torque. I want to make them move with a motor. However I need it as little as possible. So after doing research I found tiny motors that are around 4000 RPM. It doesn't mention the HP...- zach_wildmind

What height can a pressurized N2O cylinder reach at 60 bar?
that makes sense then. And yes I will think of this in the future. It is my bad. English is not my first language.- zach_wildmind

What height can a pressurized N2O cylinder reach at 60 bar?
So after looking at the Wikipedia link it should be around 142 MJ/kg... So its a lot more than N2O now.- zach_wildmind

What height can a pressurized N2O cylinder reach at 60 bar?
Ok after looking online I found it was around 46 kJ/kg. So N2O has more force?- zach_wildmind

What height can a pressurized N2O cylinder reach at 60 bar?
Hi thank you, after doing a bit of research I found that for N2O it gave 396.3 kJ/kg to compress and I found that the Falcon 9 rockets gave 7600 kN of thrust.- zach_wildmind

What height can a pressurized N2O cylinder reach at 60 bar?
Hello, I am trying to understand the maths/physics/chemistry behind this situation. Here is the scenario. I have 8 grams of pressurized N2O in a cylinder at 60 bar/ 900 psi. If the temperature stays constant (let's say 50-70°C, or at a temperature where the N2O can stay as pressurized as...- zach_wildmind

Undergrad Time till the air pressure is gone
I will simply assume that remains constant as all I need is an approximation of time. Thank you very much!- zach_wildmind

Undergrad Time till the air pressure is gone
wow, that helped a lot. Given the speeds I can now approximate the time. Thank you- zach_wildmind

Undergrad Time till the air pressure is gone
Hello, I have a 8 gram cartridge of N2O meant for kitchens. Long story short from what I understand it has 10 cm cube of N2O inside. I also know it has 900 psi / 60 bar of pressure inside. The cylinder is exactly like this image. I am trying to find out how much time it would take if I...- zach_wildmind
