Friction is present yes but friction seen at the drive motor is reduced by each stage is passes back from the friction generating stage. For example the friction at the forth gearing stage gets reduced by three multiplicative stages as it’s reflected back to the driver motor. Sorry for the nerd out but this is what I doI actually watched that a week or two ago. pretty interesting. its crazy how that stuff works. I am curious if it does work, and how you even maintain that as obviously no battery could ever run it.
at that scale you have to think friction plays a major role. not just the gear reduction. you "spread out" the same amount of force over larger and larger areas the friction is going to play more of a part. whatever engine that has may not have the horsepower to turn all those gears.
add in flaws with assembly or 3D printing those pieces, and there is a ton that could go wrong.
pointless but cool to think about.

That owl will turn before I understand what you just said.Friction is present yes but friction seen at the drive motor is reduced by each stage is passes back from the friction generating stage.

If you tried to spin the shaft at the motor end with you fingers it would spin relatively easy. If you tried to spin the shaft at the owl end it wouldn’t budge. Let’s say the gearing is 100,000:1. 1 in-oz of friction at the motor end becomes 100,000 in-oz of friction at the owl. 1 in-oz of friction at the owl is 0.000001 in-oz of friction at the motor.That owl will turn before I understand what you just said.
Oh yeah multistage gearing can generate some crazy numbers but it’s not money for nothing. The efficiency takes a hit too. I model each straight cut gear pass as 95% efficient. So if you have 10 stages of gearing the efficiency is only .95^10=0.599like one atom of angulariity every week or year, century..lol kinda wild.
I was standing on the bed railing of one of the F250s today securing a ladder on the rack. I stepped down to the tire like I have 1000 times before but this time I missed. Since my right foot was still on the truck this flipped me upside down and I landed hard on my back in the gravel lot at the shop.
Everything hurts.
Nothing broken.
Hope yall had as good a day as I did.
No.Ouch, hope for a full recovery. Did you get checked out by doc?

No.
That’s what smart people do.
My thing is if you’re going to be stupid you gotta be tough.
But seriously, the Redhead worked trama and the cath lab till she retired as an MRN. She looked me over and said I didn’t have to go to the the doctor.
Obligatory. For some of us, it's more like
" Rules to live by". Glad theres no broken bones or medical bills.
Glad nothing is broken. The old saying is if the horse throws you, you're supposed to get right back on. Is that true for trucks, too?I was standing on the bed railing of one of the F250s today securing a ladder on the rack.

Be careful, man. Lot of folks down here at Shepherd from stories just like that one.I was standing on the bed railing of one of the F250s today securing a ladder on the rack.
