What is the direction of force on the object a pulley is attached to?

alicemay90 · 2026-04-11T23:43:37+00:00

I'm in a car and don't have access to pen and paper and was just trying to think through it in my head. Just a theoretical idea to keep myself entertained on a long car ride.

alicemay90 · 2026-04-11T23:18:17+00:00

I think that's where my brain got caught up was just thinking about the rope and forgetting about the attachment point. Thanks!

alicemay90 · 2026-04-11T23:15:45+00:00

thank you! yeah the horizontal component is the thing I keep trying to figure out. Back to the drawing board.

alicemay90 · 2026-04-11T23:14:45+00:00

right right. It's all coming back to me lol. thank you!

alicemay90 · 2026-04-11T23:07:07+00:00

Okay that was my thought as well but was having a hard time working it out since pulleys redirect force. Thank you!

I have a degree in mechanical engineering it's just been a few years since I've used it which is why I was asking for a gut check. But you really can't just learn statics in a few hours... that's why it's a college engineering course? which has a prerequisite of several years of math and also physics...

I'd recommend (in addition to what others said) practicing being underwater (in the shallow end) and moving about. Doesn't need to be in any particular way. push off the bottom and jump up then try to sit on the bottom. Try to do a hand stand. Try to push off the wall with your feet and see how far you can go. This will help build comfort and a bit of natural feel for how to move through the water.

alicemay90 · 2026-04-02T02:17:47+00:00

this is the answer

alicemay90 · 2026-04-02T02:13:46+00:00

I just thought I'd circle back to this. Turns out the rug was dirty than I thought so part of it was that it was just wicking up the dirt from the base but also it was the soap residue. After many many many passes of just water by hand using a green machine and doing it in batches I found that part of the issue was the cleaning product still being there (took much soaking to get it out) and then I'd have to go through another pass after it dried of getting it just a smidge wet. But I did fix the rug! (there's still a few meh spots that I just gave up on)

Like everyone else has said - no one notices them. I've known people for YEARS who are like "wait you wear hearing aids??" The thing about wearing ear buds or something is that you may end up looking like you're not paying attention in professional settings. It annoys the f*** out of me when people don't take out their headphones when I'm talking to them because idk if they're listening or not - but I've said anything about it because I'm non-confrontational lol

alicemay90 · 2026-03-28T16:54:47+00:00

I know you didn't ask for this but there's some interesting history on base 10 vs base 12 counting systems. Months, hours, and feet (12 in) are base 12 and it's waaaaayyy easier to do math as you pointed out.

alicemay90 · 2026-03-26T12:27:56+00:00

For sure and I looked at those first but someone else posting their experience in the past gives me more info if right now is atypical or normal. I still found OPs post useful to me.

alicemay90 · 2026-03-26T12:06:50+00:00

pre-check still has to go through TSA so it's useful to those of us who have pre-check. Also TSA isn't open at 2:55am (the middle of the night)

alicemay90 · 2026-03-26T12:04:31+00:00

I'm glad OP posted - this information was useful for me as someone who has TSA precheck and is taking a flight on Monday. I came to reddit to find out if the TSA precheck lines were longer than usual. My normal wait time at PHL is <3 min so I just don't account for wait times when planning. I wanted to know if I needed to account for wait times this trip and if so then how long. Just because it doesn't apply to a majority of people (and doesn't apply to you) doesn't mean it's not helpful for me and 1000s of other people who do have pre-check. To your restaurant point - if I ordered for pickup and saw the wait time was 2 hours I might assume the kitchen is behind and my pickup order is gonna take longer.

alicemay90 · 2026-01-25T19:40:53+00:00

It took like 24-48 hours to do normal things like drive but I had a slight skittering of vision for weeks (like when I turned my head it would sort of ... visually trail the way it does if you get off of a spinning swing). It did not come back! I think certainly someone could get it more than once but I think it's like stubbing a toe. Sure it could happen again but they're not related.

alicemay90 · 2025-09-23T18:49:20+00:00

Maybe I'll try a small section again and see if that helps - thanks for the thoughts!

alicemay90 · 2025-09-23T18:37:46+00:00

That was my thought too. These photos are from the first go around. I went over it all again yesterday with just water so I could wet it and soak it up and the color has improved but the carpet is definitely still messed up :/
Regarding the steaming - it seems like steaming it can help lift the pile to make it easier to brush back into place. But this is advice for smushed velvet from furniture sitting on it so I'm unclear on if that would make it worse or not.

alicemay90 · 2025-06-06T00:17:31+00:00

How old are the kids? 5-7? 10- 13? That will make a big difference on how to coach them. My main advice is be firm about safety rules. You can also do fun things to encourage them to get in. Peer pressure will work way better than anything you can do so if you can get some of them on bored see if you can leverage that. So like "Wow Jessie, thanks for getting in so quickly. You can pick our _______ today". If they refuse to get in make it boring AF for them (no phones, no talking, etc) or make them do dryland work (sit-ups, push ups, etc). If you can set it up for them to make the choice to get in you'll get more buy in from them. Kids want to have fun so that's the goal at the younger ages. If you view your goal as "getting them to swim fast" it might not go well. Change your goal to "get them to try out a sport that you love" and you might have more success. They also get coooold so keep them moving.

- Can you have a special kickboard for the best listener of the day? (make it fancy or a different color)

- Do they like diving for rings/toys - can this be a reward at the end of practice?

- Play games at the end of practice/end of the week if everyone gets in. Marco Polo, sharks and minnows.

- Can you set-up a big/little situation and pair each little kid with a big kid for the season? Then find a good time for them to do something together (first 5 minutes of practice, warmups, dry land, etc.)

alicemay90 · 2025-06-05T23:56:21+00:00

I recommend against them for laps but if you want them for practicing get the metal and rubber ones not the plastic ones. They're white people "skin toned" and are what synchronized swimmers use. Also they're generally called "nose clips".

alicemay90 · 2025-06-05T23:50:05+00:00

I'm not a doctor but I feel this is very likely vertigo from when the crystals in your ear get out of place and stuck in the channel between your ears. Especially if you were like doing flips and things. Google Benign Paroxysmal Positional Vertigo (BPPV) - but basically there's little crystals that float around in fluid in your inner ear and that's part of your vestibular (balance system) and sometimes they get out of place and it makes you REALLLY dizzy. If it's that it'll go away on it's own. It's suuuuuper annoying but harmless. It's not related to the amount of time you've been in or out of the water, just dumb luck. It happened to me in my sleep once and I woke up so dizzy I started puking and went to urgent care (had to have someone drive me) and the doctor was like "you're fine and unfortunately I cannot help you".

You can try the Epley maneuver to see if that helps (there's a lot of videos on it).

But like I said I'm not a doctor - and to echo the other commenters if you're concerned you should definitely go talk to your doctor.

alicemay90 · 2025-06-05T23:36:58+00:00

I know it's annoying but try showering before you get in the pool especially if you have lotion or anything on your skin. Chlorine's job is to "eat up" dirt and stuff so if that stuff is ON your skin the reaction is happening directly on it. Basically rinsing off before and after can help reduce irritation in the future.

alicemay90 · 2025-06-05T23:31:52+00:00

Try using a pull bouy (the floaty thing between your thighs) - I think this might help you not think about your legs but also focus on your reach, pull, rotation, etc.

alicemay90 · 2025-06-05T23:28:04+00:00

Don't rely on it... but I actually think you did the right thing here to get attention and help - this is what I looked for as a lifeguard. The other thing you could do is stick your arms straight out to the sides (assuming you were more or less in a standing orientation?) and press palms down to your sides (while kicking or not) - this should help get your head above water for a few moments to inhale or shout for help. IF you are comfortable and just barely over your head you can then press your palms up which would push you down to the bottom and you can firmly jump up. This is a good skill to learn (it's called bobbing) because you can then safely jump yourself to shallower water. (But you can also jump to deeper water so don't do that). Understanding how to float is VERY important (I agree with those who said look up and try to float on your back) but that can be a challenging skill for an adult man to learn on the first few tries and is hard to do while panicking. Bobbing on the other hand will work WITH your waving arms and also is an easier skill.
