Hi! I can't understand, why seconadary forces are 2x per revolution? why from 0deg to 90deg secondary force curve goes down, and from 90deg to 180deg curve goes up? can someone explain?
 
Correction to an earlier post of mine where I said "Each sine wave is twice the frequency of the previous.
"


Should be "the frequency of each sine wave is a multiple of the fundamental frequency"

Engineering is the art of creating things you need, from things you can get.
