Motorized Toy Car Challenge video devloped to illustrate concepts in the curriculum: gear speed and direction, circumference, diameter, radius, combining different size gears, driver gear vs driven gear, gear trains, gear ratio, gear friction, gear pairs (compound gears), lever arm, torque, rim force

This is the best video on gear ratios and compound gears, and it seems so ancient.

@@zeroone171 The curriculum was actually made almost 30 years ago, in 1990. 10 years ago is just when they uploaded it to youtube. Of course this only supports your point further though, the other guy was just being a whiny bitch about the noise. I definitely never noticed anything even mildly distracting, much less "unlistenable." Probably just some kid who's only ever listened to audio recorded after 2010 with crystal clear audio recording equipment.

boowonder888 KZfaq. Google. An internet with literally countless websites containing free guides and reference materials all made readily available to anyone 24/7/365?? I don’t think anything good would’ve came from it if I had that type of knowledge at my disposal when I was a kid to where all I had to do was literally reach into my pocket at any given time and pull out a phone to get any question I could ever possibly think of answered immediately. That would’ve most definitely been a recipe for disaster

Nice video , he should mention that when decrease the speed it increases the torque. That's how a car transmission works. When a car starts running it engages the driver gear to the largest driven gear and then starts shifting until get to the smallest one.

@icedragonfilmz146 7 жыл бұрын

I like how giant gears turn tiny gears fast and when you connect another giant gear to the tiny gear, that giant gear spins as fast as the tiny gear. Continue this process a hundred times and you get an extremely fast spinner. One day you could just turn a handle slowly for a minute and get a fast spinning fan for a minute I just love gears

@kirara4953 3 жыл бұрын

Basics of transmission: 1:1, output will be the same as the input. 1:2, output will be twice the input. So one input rotation will be two rotations of the output. Effectively covering more distance in the same amount of time. Speed is distance x time and so you get a higher speed. 2:1, output will be half the input. How does this multiply torque? IDK, it just works.

You can try to think of it as relative rotation speed. If red gear is spinning 2x faster than yellow, and yellow is 1.5x faster than blue. How much faster is red than blue? (2red/1yellow)*(1.5yellow/1blue) = 3red/blue, as the yellows cancel in out. Resulting in 3 to 1 ratio red-to-blue.

I've been googling sprokets and v belt pulleys. Looking a struck mini dozer. Bely drive system, trying to build a mini mover but with tires, not hydraulic.drive.. the belt drive mixed in with chain and sprokets... watched a few kit assemblies... then i caught it .... its the chain drive that sets the center (gear) that goes in the opposite direction.. the chain drive runs constantly with the engine, the belts are hooked up to the lower shaft the other to the middle thus the reverser. Quite intresting... I may build it to look like a riding mower, and just say its all wheel steer and all wheel drive. AWDAWS.. THEY MAKE THESE THINGS....
