How can a long, cantilevered bridge stay up? What are the forces behind the stone towers of a masonry bridge? Forrest Wilson, award-winning author of What It Feels Like to Be a Building, tackles these basic engineering principles involved in bridge design. In this playful book, Wilson clearly shows children (and anyone else new to engineering) the mystery behind bridges.

Wilson ( What It Feels Like to Be a Building ), a professor of architecture at Catholic University, here conducts an erudite but playful lesson on the principles of bridge constructon. He conveys such essential concepts as gravity, weight and mass, shows how a suspension bridge works and defines such structures as a trussed train bridge and a cantilever, ever mindful to present ideas in terms of a child's experience ("The arch stones . . . are held from pushing further by towers with the strength of elephants"). The black-and-white artwork takes full advantage of the wide, ample pages with plain line drawings of bridges and silhouettes of dogs, monkeys, elephants and primitive people who disport themselves with acrobatic facility. Unapologetically didactic, this brave book dares to introduce scientific concepts not with flashy colors or silly cartoons, but with grace, wit and intelligence. Ages 6-up.
