In MERM this term is absent so I'm pretty sure the formula in 1.1 is wrong but someone who knows...
I'm well aware of the errors in the book. I was just curios if any of your questions forced you to pick between the correct answer and the correct answer per the handbook?

@mechengineer1213 I asked this question before with no response so maybe you can shed light. The PE handbook was riddled with errors when first came out and appears to still contain some issues. Did you have any questions that required the use of formulas or information from these incorrect...
@Ijoinedbecausecovid Did you come across any questions that required use of the section in the manual that still have incorrect information? it seems most of that was in the TFS exam but I'm curious if you went from memory or used incorrect equations for consistency. Guess it doesn't matter much...
Just to stir this pot a bit more, all the PE exams before they went to multiple choice were hand graded long form problems that required a lot of partial credit for you to pass. Having spoken to those that took that version of the test, their licence is granted entirely on partial credit.
