because we have a lot of theories that might be useful in our daily life..
do uoll know abuout stress-strain graph??
sure some of u knew it already right??
okay...
let me brief uoll simple theory to understand it..
hope i'll not give wrong infos ya...
okay...
hajimemashou...
at first, the stress will increase as the strain increase..
at yield point, the material starts to deform into plastic..(not elastic anymore)
after this point..they are not directly proportional anymore..
the dislocations start to move..
the material can still withstand stress...
the maximum one we called as "ultimate tensile strength"...
and lastly, it wont last anymore..it will break at fracture point...
there are two fracture in this case..brittle fracture and ductile fracture..
brittle fracture occurs when there is no dislocation and breaking of atom inside the material..
as high loading rate or impact load applied, it will straight away break..
while ductile fracture happens as the load being applied slowly and there are lot of dislocations..
therefore, it will last quite long a bit..
from this theroy...
i realized that we human also face a lot of stress and strain thingy...
we stress to do work...
stress when we get a lot of assignment...
stress when we need to do 4 or 5 things in one shot..
can say we are brutally mental tortured..haha...
and what make us different is our toughness..which is high in strain value..haha..
in my point of view..i would rather be tough than being strong..
i would rather do and takes the job or load slowly...(ductile fracture)
compare to take everything in one shot then faint...(brittle fracture)...
i would rather be in plastic region than in elastic region...
because i would have great or ultimate strength..haha...
there are cases where someone get crazy because pushed himself too much...
oh man...this is bad..
what u should do is....
don't put too much stress on yourself...
face things one by one...
and choose the priority....
*p/s: because too much load and stress, i just happened to realized that it is 12 of april already...
oh my nike!!! i didn't write any post after end of march..haha
