In this video, we are going to focus on finding out the value of factor of safety based on the given information for two plain states according to two different theories.
00:10
So here if we talk about the first kind of theory, then firstly we can write the given information such as s of ut value is given over here as 30 and then units are kpsi.
00:22
So kpsi means kilo pound force per square inches.
00:26
And now we can say that s -u -c value is here equals to 90 kpsi.
00:36
Now here the sigma x value is equals to 2, 5 and then it will be here kpsi.
00:45
So these are the units.
00:46
And now similarly we can write the value of sigma y and that is equal to 15.
00:50
So units are same.
00:52
Now we can say that torque around x ,y, will be here.
00:57
Here equals to 0.
00:59
So it can be written like this.
01:01
So this is our tau value.
01:03
And then here we can say that sigma 1 will be equals to sigma of a and that is here equals to sigma of x.
01:10
And it will be here 25 kp s i.
01:15
And now we can here write that the value of sigma 2 or we can say it will be sigma of b and that is here equals to sigma of y and that is here equals to 15.
