Editorial Reviews

Children's Literature
Using clear, everyday examples of pulleys, the author succinctly defines and explains the physics involved. A simple graphic design shows the parts of a pulley. She then explains fixed and moveable pulleys, double pulleys, counterweights and block and tackle. She uses an escalator as an example of this simple machine as part of a complex machine. An experiment using common and inexpensive items to make an "elevator" provides the student with a hands-on way to understand the concept. Words to know, Internet sites, a brief bibliography and an index are included. This is one of six books in the high quality "Understanding Simple Machines" series, which is part of "The Bridgestone Science Library." 2001, Bridgestone Books/Capstone Press,
