Mathematical problem

Make k the subject

F/k = (m*r*(w^2))/k-(w^2)*(M+m)

this might make it more understandable


thank you for ur time and effort ^_^

 

It would be a lot of help if you could give us what type of methods to use and what kind of class is this problem excerpt from?

 

this is a physic question (rotating imbalance) as to find the value of k .. I'm dont know which method to use to make the whole equation into k = "blah blah"

 

I never took physics before but if you're just re-arranging to make k=w/e then isn't it just F/(m*r*(w^2))/k-(w^2)*(M+m)=k ?

 

F/(m*r*(w^2))/k-(w^2)*(M+m)=k

there is another k needs to be rearranged to form only 1 k

 

Ahh, I missed that. Is this txt book stuff? If it is try the solutions manual, it should show you how they do it step by step.

 

Here!

 

Just to reconfirm that answer. My end result is slightly different but it should be the same due to the signs

 

thank you for everyone 's time and contribution spent for me ^_^

Oddly i kept smashing my head against the walls and table .. suddenly the light bulb switched one *imaginary* the answer finally hit me ...

k = F*(w^2)*(M+m) / F - m*r*(w^2)
