Hi,
I am working on a problem with a free hanging mass attached to a spring and damper in parallel. I believe my system equation is as follows:
my'' = mg - by' - ky
My questions:
1) It has been a while since I've taken this course and just wanted to confirm I wrote my system equation correctly...for some reason I remember the spring and dampers in parallel add (opposite of those in circuits).
2) Where can I find or calculate a value for damping coefficient, b, assuming damping is caused by seawater ?
