So if you look at the figure, maybe you need to start defining these characters because if you look at the temperatures for instance between 260 and maybe 204 degrees celsius okay.
00:15
At 260 remember percentage elongation for that %el will be greater or equal to 12 % okay.
00:29
That is possible for maybe t time equals to 10 and minus 2 hours that is less than 10 to minus 2 hours or 10 greater than 10 hours that is for t.
00:47
Which means that for that tensile strength cannot be achieved you know because we're looking at a minimum of 425 mpa okay.
00:58
For greater than 10 therefore we're looking at tensile stress being equal less than 425 mpa right.
01:07
Then at 204 if you look closely we're looking at %el being equal to greater or equal to 12 % that is therefore means that t will be less than 10 to power 1 correct hour.
01:31
And also t greater than 10 to power 2 hours.
01:35
So these two scenarios means that the tensile strength will be 450 less than tensile strength all right or less than 470 mpa respectively.
01:49
This is the possible scenario that you're looking at here all right...
