Hello guys, i am here to solve this problem.
00:02
So in this problem, a pressurized tank was fabricated by welding strips.
00:09
So first of all, a cylindrical pressurized tank is given in our tuition.
00:16
Now we know that when a tank is in pressurized, so then there are, we calculate the hoop stress.
00:23
So what is the formula of the hoof stress? hoof trace is equal to it is denoted by sigma.
00:28
Is equal to p d divided by two t and the longitudinal stress longitudinal stress it is noted by sigma l is equal to p d divided by four t so there are two types of stress which generated in a cylindrical pressurized time now suppose we make a more circle for this condition so suppose it is a slender it is a circle so so we need to draw a more circle.
00:59
So these are the x and y xx and it is the center of this more circle.
01:04
And suppose this point is called sigma n which is equal to 0 .85 sigma h.
01:13
Upstress comma tau.
01:15
And this center is called what is the center? center is 3p d divided by 8 comma and if we draw this projection on x -axis to the center.
01:27
So this point is called because it is sigma n, that's why it is sigma n comma 0.
01:33
Now this point is also called sigma n and this point is called sigma.
01:38
It is the longitudinal stresses here...
