Synopsis
Uses everyday examples to show how wedges are simple machines that make pushing, pulling apart, and lifting easier.
Children's Literature
Using clear, everyday examples of wedges, the author succinctly defines and explains the physics involved. A simple graphic design shows the components of a wedge. Readers can then see how wedges are used to cut, split, push apart, and push together, to hold tight and to grip. The final page provides an example of this simple machine as part of a complex machine. An experiment using common and inexpensive items 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,
