Session 3: Free Body Diagrams – what are they and why do they go wrong?
30 minutes presentation, 30 minutes curated Q and A
Free body diagrams are used in structural analysis to try to reduce the problem to its simplest description.
Where does the load get applied and where does the load get reacted?
Free body diagrams can be created for the overall assembly and for each component in that assembly – hence tracking the load path.
This seems like a straightforward procedure – but in fact it is surprisingly easy to get things very wrong!
In this presentation I show a very early example from my stress office days, and talk about an industrial example that had tragic consequences.
Here is your chance to learn some new ideas, pass on tips, or generally join in the discussion!
