Question Answer
compression
crushing forces
start learning
kompresja
deform
change shape
start learning
deformować
tension
stretching forces
start learning
napięcie / zdenerwowanie
extension/elongation
subjected to tension its lenght increases
start learning
wydłużenie / wydłużenie
tensile strength
ability to resist tension
start learning
wytrzymałość na rozciąganie
compressive strength
ability to resist compression
start learning
wytrzymałość na ściskanie
elasticity
can extend but still return to their original shape
rubber Can be elastically deformed
start learning
elastyczność
stiff
strong but has low elasticity
start learning
sztywny
brittle
breaks easily
glass
start learning
kruchy
fractures
breaks due to tension
start learning
złamania
is plastic/plasticity
can change shape but won't return to original
lead
start learning
jest plastyczny/plastyczność
plastically deformed
by hamnering or rolling
start learning
odkształcone plastycznie
malleable
plastically deformed
lead(Pb)is malleable
start learning
ciągliwy
ductile
Can be drawn out (stretched) into a long lenght
copper (cu) is ductile
start learning
plastyczny
tensile testing
sample bar is subjected to a progressively increasing tensile force
start learning
Rozciąganie
proportional
start learning
proporcjonalny
limit of proportionality
beyond this point lenght increases at a greater rate than tension
start learning
granica proporcjonalności
elastic limit
beyond this point the bar Will no longer go back to its original lenght
start learning
elastyczny limit
yield point/yield
once the bar yields, it continues to increase in lenght without further increase in tension
start learning
punkt płynności/wydajność
ultimate tensile strenght (UTS)
beyond this point a waist (a narrower section) appears at a point along the lenght of the bar signalling that its about to fracture
start learning
granica wytrzymałości na rozciąganie (UTS)
fracture point
where the bar breaks in two
start learning
punkt złamania
metal fatigue
start learning
zmęczenie metalu
cyclic loads
forces that continually vary
start learning
obciążenia cykliczne
flex
bending up and down
aircrafts wings frequently flex
start learning
zgiąć
