(Forgive the messy working someone has done on this). This is an excerpt from an engineering textbook that I would like to get my hands on. This is pages 188 and 189.
Sorry it is very vague
, the only other information I can offer is that the textbook is somewhat old and has a distinct orange square at the top corner on each page. If you recognise it could you please tell me what it is?
