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.

Saved a checkpoint:

Fixed the geogebra_applet() parameters to call the scaling functions.  Issue was geogebra accepts abs() but not Abs()

The geogebra_applet() function is called directly in the statement, and the diagram resumes.

The geogebra_applet() is also called and stored in a variable ggb_diagram to be used by the marking algorithm.

The custom marking algorithm fails on 'evaluating variable right_sign' after resume

Currently using the applet variable.  doesn't resume, but marking works.
