• Numbas versions of problems from "Operating, Testing and Preventive Maintenance of Electrical Power Aparatus" by Charles I Hubert

  • Engineering Statics Homework Problems. Problems have dynamic Geogebra diagrams and use the quantities extension.

    Many are included in Engineering Statics: Open and Interactive, a free, online textbook. 

  • The Numbas Open Resource Library will be a collection of high-quality open-access questions and exams.

    It is currently in the planning stages.
