So I got this idea and for some reason the pulley and cable system

I wonder if this same question was asked on 2000 B.C. /g/...

If you could use your brain you would see that there's no way this could work.

u wot m8

Basically the hand will move downward 3 times faster than the weight moves upward.

also not being retarded helps

We're too intelligent for math and physics here. Try /sci/

What exactly are you asking?

By the way these are called Atwood machines and the idea is old as time.

It's been a while since I've taken high school physics but for some reason this doesn't look like a 3:1 pulley system to me. Isn't it only 2:1?

Oh wait never mind, the second rope segment from the right is also under tension. Forgot to count that.

You can buy MATLAB and Simulink for $20K and simulate this all day, anon.

what do you even mean... Pic unrelated if thats what you were getting at.
My pops is 72 and its snowy here in the north east so Im devising an apparatus that will bring the paper to the door in the AM so he doesn't have to walk out and get it. My original pan consisted of an upper guide wire that the box hung from on wheels with the bottom having a cable and pulley system in which the cable was attached to the box and there would be a pulley on either end (think bike chain and sprocket) and at the house side i was going to set up a low speed electric motor and a switch and just reverse polarity having a bump type kill switch at the end i.e. road side.
so paper comes he hits the switch box comes down the guide wire, he gets his paper nails the switch and sends the fucker back out to the street for tomorrow.
However I think I have a better way involving less cable and I cant get it to work in my minds eye therefore I was wondering if there was anything short of CAD that could hepl me resolve my curiosity
