Question

i need to write some strengths and weaknesses on beats and their mathematical models,urgent help needed!

Answer 1

@wio @whpalmer4 i have been told you are helpful, anything is appreciated thanks!

Answer 2

@satellite73 @sourwing if you're not too busy could you help? or at least tag someone that might know how to help?

Answer 3

Can you elaborate a bit on the question here?

Answer 4

i have the model y = 2[cos1/2(f1-f2) x][cos1/2(f1+f2) x] and it is a beat function of a pluck of a guitar string
i am using the equation filled in from this: y = 2[cos2 x][cos21x]
i need to talk about the strengths of the original model and the weaknesses, like the force can change with each pluck of a string so the model would not accurately depict the proper frequency,
i hope that makes sense

Answer 5

I am no expert on this, but I did find one interesting resource by looking up "guitar string mathematical model" on google.
http://www.forskningsradet.no/servlet/Satellite?blobcol=urldata&blobheader=application%2Fpdf&blobheadername1=Content-Disposition%3A&blobheadervalue1=+attachment%3B+filename%3D%22GullaJanFys.pdf%22&blobkey=id&blobtable=MungoBlobs&blobwhere=1274491693086&ssbinary=true
I would read over this particular section for limitations/weaknesses -- limitations -- and consider some of these.

Limitations
When deriving the mathematical model for a vibrating guitar string a number of simplifying
assumptions have been done. Some of the main ones are:
 No resonance from the guitar body is taken into account
 String stiffness and its effect on the vibration has been excluded
 Damping, due e.g. to friction and air resistance, has been ignored
 The string is assumed to be in an acoustic dead environment
 The initial shape of the string when plucking is an approximation
 Other forces, e.g. gravitational force, have been ignored

I don't like to reduce this problem to "well go google it," but i figure this may generate more assistance than i could or many seem to have been able to based on the type of problem it is.

Answer 6

anyways, best of luck with this assignment. i have to get some rest.

hopefully, someone else is able to pick it up and give better input!

Answer 7

thank you so much! i really really appreciate your help! you are a lifesaver!!
