Not sure I will be able to get the help I need by posting here but I am currently stuck on a question from my Control module from my Electronic Engineering university degree.
I can get the answer down to the second line after using free body diagrams to find the transfer function of the system I was given but can not see how it has been manipulated to get the third and fourth equation lines.
Hopefully someone can explain this to me. Thank you
