Hey now, I'm not an engineer So the first time I saw this a few weeks ago it kinda blew my mind and I really had to think it through. Please don't shame people when they need to take a moment to think things through.
Hold up, I'm not shaming anybody who wants to think things through. You're more than welcome to, as you do in your regular day to day. I just think it's funny that people feel the need to over explain anything and everything on Lemmy even the troll stuff they see in a shitpost, which is very different. Don't overload my comment with a take, please, that's not what I'm doing.
Sure, but only because you asked. The magnet applies a force on the metal block, and the metal block an equal and opposite force on the magnet. The force is dissipated as a compressive force along the arm. All forces cancel out, so no net force is applied on the body.
They are connected in the same system. What the truck is doing is the same thing as you holding two magnets together, you won't go anywhere because everything is self contained.
Edit: this is probably not a very accurate explanation but it's the way I understand it.
If the arm can bend, the car and the magnet could move towards each other until they come together, moving the car at max a few centimeters. If the arm doesn't bend, the car is pulled as much forward as the magnet, and therefore the arm and in turn the car itself, is pulled forward, leaving the whole system stationary.
Then why use plural people? You pre-emptively complained about something that wasnt much of an issue and then got upset when people got excited about a silly physics puzzle/riddle?
Because it happened in another thread I was reading. It's a common pattern on Lemmy. Simple as.
You pre-emptively complained... then got upset
I did not pre-empt and I did not "complain", and I certainly did not get upset 😂🤣 What is this. If anything, I'm more surprised I'm getting this type of flack over an innocuous comment.
You're just willingly misinterpreting everything I did to paint a warped picture of me. Restrain yourself, please.
Realize that the sigh is not from exasperation but of "these silly folks" as indicated by the emoji. Jesus Christ, not only do people love over-explaining, but y'all will impulsively look for any reason for a witch hunt.
