truss no one

I couldn’t help thinking of my students when I read today’s dVerse prompt, Poetics: build a bridge” I tell them truss analysis is just like Sudoku but more fun – just lay out your equations, fill in the gaps, and truss me, that’s all there is to it! Until the build and test, that is. 

Every member – tension or compression?
Every joint – apply Newton’s second.
Have you considered load distribution?
What external forces make a contribution?

~put theory into practice~

Embody your equations in concrete and steel,
Now do the forces balance, for real?
Have you proved yourself a truss design master?
Or will your bridge feature on Engineering Disasters?
