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.

William Haynes on Truss: zero force members 6 months, 2 weeks ago

Saved a checkpoint:

Switched to all-or-nothing scoring.  No feedback.

William Haynes commented on Truss: zero force members 6 months, 2 weeks ago

Need to work on the marking algorithm to give full 20 points when all are correct.  Currently, rounding errors on some situations lead to scores below 20.  Also would like to provide feeedback.  "some zfm not selected" and "some load bearing members chosen"
