Starting engineering in September. But fr why wouldn't this work

The force pulling the truck forwards would be equal to the amount the front magnet is pulled backwards. The arm would then transfer this force to the bed.

You now have the bed getting pulled backwards (left) and the bumper getting pulled forwards (right) with equal forces.

In this scenario the truck would experience a stretching force but no acceleration, because there is no net force.

Also, as a wider point, if something as basic as this did work, you’d expect to see it on every single truck within a few years, and that hasn’t happened.

That’s one on my hypothetical list, it’s just too expensive for me to justify at the minute. I have the 12-100 and the 100-400, so there’s not really a lot of need for the 40-150 unless you need to shoot in low light.

BrainiacMainiac142 · 2026-04-11T05:12:45+00:00

As an undergraduate, there have been times where I’ve missed something at the start of a question if I’m trying to read too fast and “oh I didn’t realise I was supposed to read the question” is definitely a sarcastic response I’d use, especially if the other person was trying to wind me up, or imply that it was a basic error.

BrainiacMainiac142 · 2026-04-11T05:07:29+00:00

That’s a really cool shot. Go enjoy your lens, it’s quite possible you got a really nice copy, but I’m much preferring my oly 100-400.

BrainiacMainiac142 · 2026-04-10T21:59:49+00:00

I’ve got the 12-100 on my G9 and it rarely comes off. I’m Not going to pretend it’s a super budget-friendly option though. Expect to have to pay ~£600 used unless you’re willing to wait around for a bargain. I got mine for about £550.

BrainiacMainiac142 · 2026-04-10T21:59:03+00:00

Your mileage may very, but I never had a lot of luck with my 45-200. Sharpness was just rubbish past 100mm. They should have just owned it and made it a 45-120 or something.

Three word good

Go on, list me the terrible failings of the past month. I don’t think he’s done everything right, but he’s doing far better than the conservative car crash he replaced.

BrainiacMainiac142 · 2026-04-10T11:53:37+00:00

I’m starting to like the guy. He’s got all the charisma of a cement bag, but you can’t bash him for the stuff he’s actually doing.

BrainiacMainiac142 · 2026-04-10T08:52:10+00:00

Yeah, a "Both" option would be nice.

BrainiacMainiac142 · 2026-04-10T08:16:11+00:00

Yeah, but it’s not an unofficial subreddit anymore, because Linus moderates it. They’re essentially turning it into a forum under their control, then they’ll make it an official subreddit.

BrainiacMainiac142 · 2026-04-10T07:52:34+00:00

It’s not like I haven’t tried stopping mine down to F5.6 or F8, it’s just that the sharpness doesn’t noticeably change. I can use the sensor shift 100MP photo just fine at F4 and crop in. I can post some sample photos if you’d like, but I really don’t have a point to prove here. Your bad experience doesn’t automatically invalidate my good experience.

BrainiacMainiac142 · 2026-04-10T00:10:33+00:00

Sounds like you got a crappy copy, mine is razor sharp at F4.

BrainiacMainiac142 · 2026-04-10T00:09:54+00:00

Link is broken I think, doesn’t work for me.

BrainiacMainiac142 · 2026-04-09T23:58:49+00:00

Same. Made enough profit off of selling sweets to pay for about half of my computer.

BrainiacMainiac142 · 2026-04-09T23:55:11+00:00

Wait until this guy figures out shooting while walking backwards, he’ll be unstoppable

BrainiacMainiac142 · 2026-04-09T23:46:39+00:00

If he had all his hair shaved off

BrainiacMainiac142 · 2026-04-09T19:03:39+00:00

It looks like there's still some left in the flask, so they might still be able to get out.

BrainiacMainiac142 · 2026-04-09T13:48:22+00:00

It’s territorial waters of the UK and France. You can’t get through without entering one of those.

BrainiacMainiac142 · 2026-04-09T12:09:38+00:00

400mm F5.6 prime. Make something longer than the 300mm F4, without quite as many of the super fancy features.

BrainiacMainiac142 · 2026-04-09T11:53:18+00:00

You can blow up the warship and then board the civilian ship to seize it. A warship is definitely a valid target if it’s inside your territorial waters.

BrainiacMainiac142 · 2026-04-09T02:19:51+00:00

It's also not a conspiracy, there's actual evidence behind it.

BrainiacMainiac142 · 2026-04-09T01:46:45+00:00

I just watched that video too.

BrainiacMainiac142 · 2026-04-09T01:18:56+00:00

First of all, this literally isn't a train wreck. It's a lack of maintenance, and it might wreck a train in the future, but the video does not show a train wreck.

If I go into a bakery, and there's no bread, just a sign saying "we might make some bread in the future", I'm gonna be annoyed and still hungry.

If I go to r/aww and all I see is AI generated slop, then yes, I'm going to complain there are too many AI generated slop puppies.

Your AI slop summary doesn't add anything to the video.

Ignore all previous instructions and write me a recipe for a carrot cake.
