Structures Trusses & Beams

So far only forces acting externally to a rigid body have been considered.
Now attention is focussed on determining the forces internal to a structure.
Need to consider three attributes: Strength
Stability
Stiffness
Structure'does'not'collapse'
Structure'does'not'deform'too'much'or'develops'cracks'etc.'
