Modelling and Image Analysis
Question
For the timber footbridge shown below sketch an analytic
model of one of the supporting trusses, judging as best you can based on
the information available in the photos. Clearly indicate nodes, elements,
applied loads, boundary conditions, and end releases using notation outlined
in lecture. Briefly explain your interpretation of boundary conditions and
end releases.

Summary
New Information Types and Avenues
Digital
images significantly leverage the power of conventional slides
- Enhancement
- Annotation
- Manipulation
The web provides new avenues of information flow
- Images available outside of lecture
- Collective review through compiling student work
- Collective inductive learning by combining information gathered
by students
Further Work
Things I haven't even talked about
The
web as an information resource.
- Peaks of useful content are ever emerging in the vast plains
of cyber-dreck.
Collective review
- Compiling student-produced web materials.
Databases of student work
- Answers collected through forms
- Browse by question, or by student.
- Feedback through e-mail.
