It sure looks wrong.
I mean, it makes no sense with a dimension to a random line.
Your observations are right, and it sure looks wrong.
I've got the Machinery's Handbook 27th edition and on page 46, the definition of an elipse, see the line "a"? shouldn't it be shorter? ie: from the centre to the apex of the major axis?. They have it going fully tothe "Y" axis... this is confusing me since "b" goes from the centre to the apex of the major axis.
And I thought the eccentricity was given by b/(distance from centre toapex of Major Axis)
Confused and puzzled... am I wrong or is the Machinery's Handbook?

You are right about "a", it was corrected in the 28th edition.
Eccentricity is c/a

Thanks guys, I thought I was going bonkers.

Bonkers loopy nuts are we,
We're all into industree,
You your mates and also me,
Like breaking things with machineree.
lol Gonna stick on my CV that my maths is better than the Machinery's Handboook.
As an aside, I've also found errors in "Engineering Mathematics" by K. A. Stroud, which is meant to be the mathematics bible.

Iman.. Very nice..You are genious... If you find error in "Engineering Mathematics" by K. A. Stroud, then don't say it BIBLE....
