Homework: How many bottle openers need to be glued together so that their weight alone is enough to open the bottle without that extra nudge?

[@lowdencraft5085]

It would be a good I'm class experiment to show leverage forces

[@ancellery6430]

between 8 and 9

[@A_Baguette_]

Since units of bottle openers are discrete, the answer is 9. Units have to be discrete because we don't know exactly how much mass comes from the glue vs the bottle openers. Since other assumptions are in play though, just round to 2 decimal places, should be fine.

wow the literal inertia of the tip opened the bottle. that's impressive and mind boggling what true understanding of physics can look like

[@not-askaven2990]

"I first glued five together to see how the bottle would handle it and sure enough the glue wasn't dry" The narration delivering it with no surprise at all is just fantastic, going directly into the full experiment as if it went perfectly

[@adamarmiya5092]

I fucking love physics. The serotonin my brain receives listening to the scientific and mathematical explanation of a banana opening a bottle is indescribable.

[@Elantiven]

Cool I never thought that just increasing the length could do so much it was a little hard to understand but cool you should try out more things using this bottle opener

[@JaDroppingScience]

Great feedback, yeah I understand that might be the case depending on people's background, hoping people will skip through the analysis if they aren't able to follow along.

[@truevulgarian]

I think the concept is torque. The longer the lever arm the more the savings. That's why manual car jacks have long handles. You don't have to be strong enough to lift a car to lift a car.

[@hadensnodgrass3472]

Who was it that said, "With a long enough lever and a fulcrum on which to place it, I can move the world" ?

[@OptimusPhillip]

@@hadensnodgrass3472 I believe that was Archimedes

[@kriiler]

Yep Torque = Fxd = Fdsin(theta) which is what he meant by force applied has to be perpendicular to the bottle opener length.

[@HarryBalsark]

Never seen anyone using an opener like this pushing from the top down. I’ve always pulled upwards, seemed a lot easier

[@robinhoodwinker8621]

Yeah that way requires even less force. Maybe he did it like this just because the apparatus is easier to set up

[@JaDroppingScience]

You'd have to hang it over the edge of the table if you did it like normal because the bottle opener would go lower than the surface of the table.

[@Altrop]

Uh I work at a bar and it's much quicker to push from the top down. Pulling from the bottom is a weird movement, you have to sort of put the bottle through the hole in the opener first. That extra half a second is precious. I only pull from the bottom with tiny keychain openers. Pushing down is way easier than pulling up btw, requires more force because gravity pulls down.

[@sylasviper715]

@@Altrop shouldn’t you pull up to have your arm in position to move on better, rather than your arm going down and then you have to lift it back up again. Those 0.5 seconds add up.
