Children's book from the 70s with cross sections of vehicles

It is not Cars and Trucks and Things That Go. In my memory of it, the illustrations are more Richard Scarry than Stephen Biesty. I recall a cross section of a cruise ship, where you could see a ballroom, the engine room etc. I do not recall if there were even people pictured, or animals like Richard Scarry. I recall the size of the book being about like a giant Golden Book or so.

Not sure of the date, but I was born in 1972, so I expect it would have been from the 60s or more likely the 70s,

I had that book and several others in the series in the 90s (yard sale find, I suppose) and I am happy to report that it is What Makes it Go? What Makes It Work? What Makes It Fly? What Makes It Float?.

Here's a blog post with some illustrations: http://www.vintagechildrensbooksmykidloves.com/2008/12/what-makes-it-go-what-mak...

I can't believe how fast your response was, and yes, that is it. I had no memory at all of what the cover looked like, but as soon as I saw the picture, there was no doubt. I will be placing an order for a used copy on Amazon this week, and I thank you for ending about a month of stewing and googling. This site rocks.

You're welcome. I think this site rocks too :)
