Wow that's very informative, thanks a lot.

Hi, I am trying to design a small machine that lowers a raised weight slowly. For example if i raise the weight by 10 metres and allowed there it should start descending at 0.1m/hour. Initially i thought of a windup mechanism but i don't know how to control the rate of descent with a windup...

What i am basically trying to do is to raise a weight and then bring it down slowly. I am not sure how to go about this. Any tips towards this design goals i appreciated

Nice idea. However, i don't have the luxury of something periodic happening like a pendulum. Am curious how do timed windup switches like the ones in the basement work without any electricity? That will probably provide me a pointer for design.

Yes something along those lines. What is it called so that i can google it and learn more of the mechanics behind it.

Hi, I am thinking of a device, i don't know if a similar one exists already but this is what it is supposed to do. 1. compress(or extend) a spring by way of some mechanical force like turning a wheel(this wheel could very well be that of a bicyle) 2. Once the spring is compressed(or...
