William Haynes on V and M function - concentrated loads 2 months, 2 weeks ago

Saved a checkpoint:

Changed accuracy to 3 signifigant figures for equations.

William Haynes on V-M 5: Symmetric parabolic loading 2 months, 2 weeks ago

Saved a checkpoint:

Swapped out old ggb diagram for improved version.

William Haynes on V-M 5a: Arbitrary parabolic loading 2 months, 2 weeks ago

Saved a checkpoint:

Made significant revisions.  Now student is shown shear and bending moment curves, but must integrate the loading to determine the shear and bending moment functions themselves.

William Haynes on V-M 5a: Arbitrary parabolic loading 2 months, 2 weeks ago

Gave some feedback: Ready to use

William Haynes on V-M 5a: Arbitrary parabolic loading 2 months, 3 weeks ago

Gave some feedback: Should not be used

Saved a checkpoint:

Starting modifications.

William Haynes on V-M 5: Symmetric parabolic loading 2 months, 4 weeks ago

Saved a checkpoint:

Continuing cleanup and formating.  Need a signal for part opened, to display V and M diagrams.

William Haynes on V-M 5: Symmetric parabolic loading 2 months, 4 weeks ago

Gave some feedback: Needs to be tested

William Haynes on V-M 5: Symmetric parabolic loading 2 months, 4 weeks ago

Saved a checkpoint:

Multiple changes:

Load ggb from file, eliminate graphics 2 since not needed.

Determine functions in Numbas to get proper simplification

Add steps to show how to procede.

William Haynes on 35. Internal Forces 3 months, 1 week ago

Saved a checkpoint:

Replaced Internal Forces: distributed load problem with an improved version

William Haynes on Internal Force: distributed load 3 months, 1 week ago

Saved a checkpoint:

Revised old version by fixing errors and improving the geogebra diagram and free body diagrams.  Old version accidentally got deleted, so question number changed.
