Re: 1190: "Time"

Apologies for the double-post The far left edge of the sand has a tiny, tiny slope upwards (present in both this one and the previous frame). I think this means that there's more to the sand castle than we see. http://i.imgur.com/Yz9es5d.png Also where is the missing vertical feature from the mini ...

There are lots of things you could do to keep it from the plagiarism search. a private Google doc that you share the link of, or upload it as a jpg on your favorite host. It certainly sounds interesting keep up the good work

Well you could use your favorite tone generation software (Audacity is free) and see what frequency(s) the buzzing occurs then doubling the mass should cut the frequency by a factor of 4.

Re: Modifying Resonant Frequencies

Changing amplitude != Changing the frequency


But would obviously change the amplitude the door is resonating. Just glue some additional masses to anything resonating I believe the frequency response is proportional to (k/m)1/2 more mass lower frequency. Or weatherstripping and caulk
