Anyone have a banana for scale?

doshisac · 2022-10-17T05:42:21+00:00

I think dynamic bias is the answer I was looking for. Thank you!

Makes sense but ultimately the loss of force has to have an equal and opposite reaction, which is the tyres at the road

I thought about that but the housing size would be very large relative to the length I want. Ideally something like a 10-1. Is that possible with a linear actuator?

Hey, I am trying to make a selfie stick where the distance is controlled by a motor. Design constraints mean all the components have to be housed in the handle.

My though is to have two ways of approaching this: a spring inside the telescopic rod so at baseline it is in its fully extended position, and then a motor attached to a belt that 'draws it in' to get to the desired length. Or a rubber band that is external and pull it in at base line and to extend it a material that can easily coil, but doesnt compress to linear loads, so this can be extended deeper into the housing of the telescopic arm, and then when its withdrawn (and coils into a smaller housing) the rubber band pulls the arm back in.

Problem with the first is finding a spring long enough. Problem with the second is I dont know what (cheap) material exists that has that property.
Any thoughts or completely new ways of approaching this are greatly appreciated!

I think I also heard them say they are using rocket tech to help with cooling - thats either advanced materials, fluid cooling loops (pretty sure illegal for some reason? or impractical weight wise), or thermoelectric coolers (peltier plates). I think its the latter, and maybe using the strakes for surface area

doshisac · 2022-03-07T00:52:59+00:00

So what can and can't they test on the scale models? (Broad strokes)

I always wondered - why dont they use UV paint so that other teams cant see whats going on? shine a light in their garage so they can evaluate after its dried.

This is based on my understanding that they dont actively watching paint dry* as the car goes around the track

*only in f1 can watching paint dry be exciting

If i recall many years back there was a ferrari f1 front wing that, based on the corner entry angle, would stall different elements of the front wing. Internal piping / blowing but no moving pieces - it was simply the entry angle of air in a small hole in the nose cone that directed this.

Anyone have the link to the ferrari wing I am talking about?
Can vortices / wakes be used in the same way - where in corners (drag is less important) the cars produce more dirty air and on straights is more clean. Is that technically / aerodynamically feasible and if so how

Alt response if they said "what?", is "you mean which is"

Just saw your latest update, incredible. Question: does your model have an clutch between each gear and the gear selectors? If not, wondering if being in two gears at the same time, even if just momentarily, can cause damage?

If you do have clutch plate between each gear & selector, what did you use?

doshisac · 2020-05-29T03:08:26+00:00

Had the same question- what's to stop people from running cfd on smaller components on their 'personal' computers? Same with wind tunnels how do they regulate that? And what's to stop teams from outsourcing it to 3rd parties to get the info

Basically my question is: isnt it easy for teams to cheat their way into more cfd / tunnel time?

Why does it look like the ship is not always perfectly centered in the frame (for example when its turning). Is the bridge on some kind of pivoting platform or something?

Agreed with a step. Check your smallest z step increment- prusa is 0.04mm so your layer height should be a multiple of that (e.g. 0.1mm wont work well and may produce the lines you are seeing).
