Positively interesting! Thanks a lot to both of you for responding soon.

At the moment, I am only interested to know the minimum force required to set the system in motion. As I was dying to get a confirmation from experts like yourselves.

I will be using this info for the experiment I am conducting, some sort of a 'self-generating power generator'. Sounds absurd, right?

I am interested to use EJS, I'll check it out. Thanks again, I'm enlightened!
