AI Thread Summary
In a job hunting context, a user seeks clarification on a mechanical aptitude test question involving interconnected gears of different sizes. The drive gear is a nickel, with a quarter (A), a half-dollar (B), and a dime (C) as the other gears. The user believes the smallest gear, the dime (C), will make the most revolutions due to its size. However, they express uncertainty because of the stepping up of the two larger gears before it. The discussion concludes that in gear arrangements, the smallest gear typically makes the most revolutions, but the presence of intermediate gears does not affect the speed of the drive gears.

OK, so I'm looking for a job! I have had the same mechanical aptitude test3 or 4 times, and I just can't find an answer to one question that I really want to double check, just to make sure I am right. So here it is; There are 4 gear, just to ease the explanation I will say them like coin sizes. On the left is a nickle, it's the drive gear. Then you have (A) Quater (B) .50 cent piece, and (C) dime. These are placed like interconnecting gears. The question is which makes more revolutions (A) (B) or (C). Now, I believe it's (C) the smallest gear, a step smaller than the drive gear. However I am unsure because the 2 gears before it step up then step up again. So, which one makes more revolutions? Am I right?

the smallest 1 will make the max revolutions...
 
Another way to look at it is in-between gears make no difference. You could have a dinner plate sized gear between two nickels and the nickels would both turn at the same speed.

That's why you hardly ever see this type of arrangement in real life, it's basically useless except for direction changes.

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...

Thread 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly
