Can anyone really explain how pulleys work? I mean not in theoretical terms

Date: November 22nd, 2025 8:19 PM Author: Deranged piazza hominid Pulleys work by using a wheel and rope to multiply force and change the direction of a force, making it easier to lift heavy objects. A single, fixed pulley can change the direction of force, while a system of multiple pulleys (called a block-and-tackle) provides mechanical advantage by distributing the weight across more ropes, requiring less force to lift the load, but over a longer distance.

Date: November 22nd, 2025 8:20 PM Author: hideous pearl half-breed stage Is it because you effectively negate the weight of gravity by transferring the load from up to down? But then why does the effort required to lift the load decrease with every additional pulley system? |
|
Date: November 22nd, 2025 8:33 PM Author: Hot Laughsome Puppy Nursing Home cq. if anything it seems like a system of two pulleys would “unreverse” the gravity, thereby rendering it useless. kind of like a “double negative” for the wordcels out there.

|
Date: November 22nd, 2025 11:31 PM Author: Hot Laughsome Puppy Nursing Home after thinking about this, the solution is kind of obvious. a dual-pulley system would have the second pulley upside-down, thus reversing the gravity twofold. in this system, the rope isn’t used to exert force but rather to keep the load from floating away.

Date: November 22nd, 2025 9:03 PM Author: hideous pearl half-breed stage Unrelatedly, are pulleys a sign that God came down and inspired us by showing through one of the profits that this is a pulley? And if that happened millennia ago, is it still happening now? Are today’s rich and famous really prophets chosen by God? Will Elon Musk and Sam Altman lead us to Nirvana? |

Date: November 22nd, 2025 9:48 PM Author: soul-stirring indecent lodge I miss college physics.

Date: November 22nd, 2025 9:46 PM Author: arousing mediation center A pully reverses the direction of the stress tensor using centripetal force. (Or maybe it's centrifugal force. Pretty sure it's one of those.)
If you get really deep into the physics, the mass of the pully actually exerts a geometrodynamical force that acts upon the field containing the rope. |

Date: November 22nd, 2025 9:49 PM Author: razzle massive school cafeteria national security agency I just watched a YouTube video of a dood restoring an old jeep, and when he sprayed lube into the stuck alternator he also sprayed it all over the belt.

Date: November 22nd, 2025 11:25 PM Author: Cobalt seedy station Its all about the displacment of gravity. If you put a couple pulleys together, it confuses the gravity molecules and they stop pushing down on the object you are trying to move, hence, the object stops feeling heavy and you can build things with large blocks such as pyramids, and also places like Nan Madol. The more pulleys you place together, the more confused the molecules becomes, its rather simple akshully (http://www.autoadmit.com/thread.php?thread_id=5801213&forum_id=2).#49453176) |
