bug reported
William Haynes commented on Internal Force: distributed load 8 months, 2 weeks ago
Neatened up geogebra diagram.
William Haynes commented on Internal Force: distributed load 8 months, 2 weeks ago
Fixed bug. Part labels did not agree with gaps.
William Haynes on Truss: zero force members 9 months ago
Saved a checkpoint:
Switched to all-or-nothing scoring. No feedback.
William Haynes commented on Truss: zero force members 9 months 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"

Saved a checkpoint:
Try to make the members clickable
William Haynes commented on Truss: zero force members 9 months ago
Found and fixed several errors
William Haynes on Truss: zero force members 9 months ago
Saved a checkpoint:
Bug reported. Seems to be indicating the wrong number of zero force members
