Hi,

i need to write the differencial force equation for the system attached,

and i am not sure if what i do is right.

when:

F- externa power

m1,m2 - mass

x1,x2 - mas location

3. The attempt at a solution

This is what i got:

for m1:

F-k*(x1-x2)-D*(x1'-x2')=m*x1''

for m2:

k*(x1-x2)+D*(x1'-x2')=m*x2'

what do you think?

thanks!
