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.

Project activity

○

William Haynes on V-M 5: Symmetric parabolic loading 3 years, 8 months ago

Saved a checkpoint:

Swapped out old ggb diagram for improved version.

○

William Haynes on V-M 5a: Arbitrary parabolic loading 3 years, 8 months 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 3 years, 8 months ago

Gave some feedback: Ready to use

○

William Haynes on V-M 5a: Arbitrary parabolic loading 3 years, 8 months ago

Gave some feedback: Should not be used

○

William Haynes on V-M 5a: Arbitrary parabolic loading 3 years, 8 months ago

Saved a checkpoint:

Starting modifications.

○

William Haynes on V-M 5: Symmetric parabolic loading 3 years, 8 months 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 3 years, 8 months ago

Gave some feedback: Needs to be tested

○

William Haynes on V-M 5: Symmetric parabolic loading 3 years, 8 months 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 V-M 5: Symmetric parabolic loading 3 years, 9 months ago

Gave some feedback: Should not be used

○

William Haynes on V-M 5: Symmetric parabolic loading 3 years, 9 months ago

Saved a checkpoint:

Prior to changes to determine function within Numbas

○

William Haynes on Truss: Solve a joint 3 years, 9 months ago

Saved a checkpoint:

Fixed intermittent bug in solution.

○

William Haynes on 35. Internal Forces 3 years, 9 months ago

Saved a checkpoint:

Replaced Internal Forces: distributed load problem with an improved version

○

William Haynes published Internal Force: distributed load 3 years, 9 months ago

○

William Haynes on Internal Force: distributed load 3 years, 9 months 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.
