Reaction to Forces (Leaving Cert Construction Studies): Flashcards

Material's ability to return to original shape after force is removed

Elastic: temporary; Plastic: permanent deformation

$\lambda = \frac{\text{stress}}{\text{strain}}$

Amount a structural member bends/deforms under loading

Longer span length and greater applied force magnitude

Compression (material squeezed together)

Tension (material stretched)

Neutral (minimal stress)

All applied forces must be balanced for stability

For every action there is an equal and opposite reaction
