Hello All,
I was recommended this book by a fellow HBA member. I am going through it and sadly I am on page 4 with a question. Did not get too far..:lick: I have attached a few screenshots below with a question.
So if I use my thinking that the 200-4 is a typo and use 204-4 I get 200lt = 5800 which gives an answer of LT=29 and not 27 as shown in the book... Can someone check this for me?
Been a while since I worked these sort of calculations so as I said it could be all me that is incorrect but I really want to go through this book and learn as much as I can.
Best regards,
Marc

- I need to solve LW going through the offset points in the drawing. First off I think the equation has a typo and thus the answer is wrong but then again I could be wrong. I think the first part of the equation should be Lt x (204-4) and not (200-4) Can someone verify that there is an error here or not and it should be (204-4)?
- On the fuselage diagram, should the elevator be on the 8" offset line and not in line with the thrust line? Or do they really want to figure out the force of Lt 8" below the elevator?
- the other part I can not figure out is where does this part come from? -(1000 x 4) = 0 I cant seem to sort out why its 1000 x 4? Im a bit rusty on my algebra equation manipulation so it could just be me...
So if I use my thinking that the 200-4 is a typo and use 204-4 I get 200lt = 5800 which gives an answer of LT=29 and not 27 as shown in the book... Can someone check this for me?
