Pulleys and Gears introduces the basic principles of these simple machines. This book looks at pulleys and gears in action, examining how a flag is pulled up a pole, how an escalator works and the differences between a hand drill and an egg whisk. Pulleys and Gears also includes a special activity with step-by-step instructions on how to make a toy windmill.
