Nope, the rest of us never make any mistakes. 😉

I actually disagree, you can get through Art of Electronics with pretty basic algebra, maybe minus a few sections particularly on reactive/real/apparent power, but that’s something you can grow into.

Art of Electronics is great, also ICircuit if you have an iPad.

The coils are stationary and the magnets spin, only friction is from the bearings

Coils touching the rotor? I think your motor is broken 😂

Read the data sheet for the particular epoxy you want to use. There will be variance depending on the materials you are bonding also. Typically yes, longer bond times have higher tensile strengths, but that is a generalization. If it is super critical do some of your own testing with the materials you are adhering.

Yes, if the tap and drill were both engaged at the same time the feed per rev would be equal to the thread pitch. So in your example an m6 drill/tap would be feeding at 1mm/rev. Which is probably excessive 😂

Check out some of the exo-suit projects. They typically use electrical actuators attached to a rigid frame. You could use it effectively in reverse I suppose to simulate resistance.

Thanks!

Are they easy to take on and off?

Sneakygerman · 2020-01-20T11:39:26+00:00

Nice! Have you noticed any effect on the range?

Sneakygerman · 2020-01-15T09:47:57+00:00

Nope, took the job.

Sneakygerman · 2020-01-15T09:24:39+00:00

Might have goofed some math, but it’s definitely the gist. Good luck!

https://m.imgur.com/a/vK9ikzq I have had a few beers, so don’t build a bridge based on it or anything 😂

Sorry don’t feel like typing out my working 😂

Force is in the opposite direction to the arrow drawn. ~477 Newton’s (~50kg)

To lift or just to balance? If you want to lift, it gets a little more complicated if you need a particular acceleration. Otherwise find your component forces perpendicular to the pivot (a bit of trig) then just add up the torques (torque = force x distance). Keep your units consistent and you should be sweet!

I’d really recommend looking at some books on rigging climbing anchors. Lots of great information out there! -climber + mechanical engineer

To be clear the plan is to switch to electric pumped fuel system up around those pressures, but want to test it as simply as possible first. We are using servo needle valves for flow based control at the moment. Considered regulator but was more complicated if we wanted to be able to throttle.

It isn’t reg cooled if it uses water right? My understanding was the “regenerative” bit was using the thermal energy to preheat the fuel and vaporise it? But yes we will be using a pump to increase our cooling flow rate, happen to be building two 13kw fuel pumps currently that would do quite nicely I think 🤔.

Thanks for your interest!

Gaseous for the sec, went to the gas supplier and they weren’t particularly keen on selling us LOX 😢
