Description

One pulley can be used to change the direction of the force applied by a cord. Several pulleys can be used to make this simple machine. A small force on the cord can be used to lift a large weight. Experimenting with the device shows why: lifting the block by a short distance requires that the cord be pulled a long distance.

Includes a detailed activity guide which details the history of the model, practical applications, and classroom experiments. Measures 13L x 4W x 6 1/2H".
