Though what I don't understand is, if a pulley reduces the force necessary to lift an object by half, if you use enough pulleys, wouldn't you be able to reduce the force necessary to reset the weight to a level that the generator could achieve by itself?

Well the only reason I am even doing this project in the first place is because you aren't allowed to use biological materials until high school...I was originally planning on doing a project on how we can advance our fight against cancer by creating drugs that target the telomeres in cancerous...

Yes, the title of the project is, "Is Gravity Viable as an Alternative Energy Resource?" I am testing different methods of creating energy from gravity, comparing them, and then concluding in answer to my original question. And I kind of did get bogged down trying to make the perpetual...

Well at that point I could just have the weight.

I don't really see where the screw comes in...

Well, I did originally plan to have the generator power servos that would raise the weight through a set of pulleys, but then I quickly realized that was obviously impossible. So now I've been thinking to use human input to raise them. What I was thinking was having the whole assembly attached...

Well the goal is to have a nut, connected to these rods that wouldn't allow it to spin, pushing down on a screw attached to a generator, making the screw turn and power the generator.

You've got the idea until the second sentence. The nut can't rotate, and the screw can. The goal is to make the nut's weight spin the screw.

Produce energy.

Well I was planning on having the nut's thread composed of two half circles that would be attached to servos that would release the screw at the end of a run, and then the nut would be raised back to its original position by a system of pulleys, at which point the servos would grab the screw again.

Calculating a Force; A Nut Pushing Down on a Screw; Science Fair Hello, I'm new to Physics Forums, and I am doing a science fair project where I am designing/building a machine, and to know if it will work/be efficient, I have to calculate a force. Homework Statement If a nut, affixed...

Yeah, that's been my main concern, it's why I set the thread to 45°. But how can I test it without actually building it? To build it I need to spend money, and before I spend any money I want to know if there is even a shot at it working, that's why I'm asking about it. By the way, The screw is...

Calculating Force; A Nut Pushing Down on a Screw Hello, I'm new to Physics Forums, and this question is not really about schoolwork/coursework, however because it is somewhat school related, I was afraid to post it anywhere else. Anyway, I am doing a science fair project where I am...
