Summary: Make a circuit that counts the number of nodes in a standing wave generator I have a an assignment to complete this Term, the assignment consist in making a machine that would produce standing waves in various frequencies, (for example the typical motor connect to a string with...

you have to remember that increased mass means increased inertia which means that it would takje more momentum to move this particle a a certain speed. if you have 3 particles in a perfectly elastic collision both energy and momentum would be conserved, you should put the equations that say...

I'm very sorry for not explaining myself correctly. The actual assignment goal is to make a toy very similar to the one in the attached file, the only difference between the one in the file and the one I am planning to make is that I will not be making a dynamo, but an alternator and rectifying...

To be more precise the generator has to be able to produce around 1.5 Watts from a person spinning its axis, which is why I was thinking of putting a gearbox in my design but I need to know how much Torque would it take to spin the axis and at what rpm would the generator be effective.
