Hello guys,
first I am sorry I didn't use the template. I deleted it by mistake and I didn't know how to create a new thread from scratch.
so I have two cases of the same problem, on with initial conditions of pulling down and the other pushing up, I tried different signs but It didn't work. Can anyone explain to me the difference in dealing with this?
thank you
