Is there a way to make a weight to pull down with stronger force?

Something like a reverse pulley, that would make the thing at the end seem heavier?

(sorry if im being stupid, its just something i cant wrap my head around)

Gearing.

pulley in op gives no mechanical advantage

if you have a pulley that gives mechanical advantage then just swap the load with the ... other bit...

do they use shit like this in gym equipment? so that they dont have to use as much mass?

You could use a lever. Twelve inch ruler, fulcrum at the two inch mark, weight at the twelve inch mark, push on the one inch mark. One pound should feel like 11, or twelve, or something. Gearing would also work, like the other anon said. Pulleys might work if they were vastly different sizes (like gearing.)

how about something like this?
>>
>>942068
so you would pull a small bit, while the thing moves up a long distance?
>>
You can do anything with gears and pulleys as long as force times movement is constant.

I think so, from what I've seen in films, having personally never attended a gym.

yea thats the tradeoff with pulleys and levers. can't beat a lever for simplicity however they can be massive but pulleys are small sized and light although the rope can get tangled.

Yes, switch the weight to the hook on the left here.
>>
>>942068
Yup

Not usually, because of what [>>942125 >>942141] said. Gym equipment can only be so tall, and using such an arrangement would increase the height stroke of the weight for a given distance of exercise-machine stroke. Now that's fine to SOME extent, if you've got a track with room for 5 feet of weight movement and the machine only moves 2.5 or 1 ft on the manual end, but if you have something where the manual stroke is very long - like a rowing machine or whatever - then your only real option is to use heavier weights (or some alternate form of resistance, such as elastic or viscous-fluid resistance).
