Calculating Horsepower, RPM, and Torque

This interactive presentation, created by James Bourassa and John Rosz for the Electromechanical Digital Library, discusses the calculation of horsepower, RPMs, and torque. Bourassa and Rosz begin by providing detailed definitions of all three topics and then provide mathematical examples for computing each measure. Once this basic explanation is complete, the authors allow students to practice these theories in a set of self-correcting quiz questions. Bourassa and Rosz explain each using interactive flash animations.Â
