We would like to find the magnitude of our applied stresses.
00:04
So we first want to find our angle.
00:06
Our angle phi is equal to the inverse cosine of u1, u2, plus v1, v2, plus w1, w2, divided by our square root of u1 squared plus v1 squared plus w1 squared plus u0 squared plus u0 squared plus u0 squared plus u0 squared plus u0 squared plus v2 squared plus w2 squared.
00:38
So for our one, so for our first angle, our angle, we want to take the inverse cosine of 1 times 1 plus 1 times 0 plus 0 times 1, divided by the square root of 1 squared plus 0 squared plus 0 squared times 1 squared plus 1 squared plus 1 squared.
01:02
And so our angle is 54 .70.
01:05
Now we want to find our applied stress for these directions.
01:16
So for our negative, we want to find lambda for negative 101 slip direction.
01:25
So now our lambda for this slip direction, we're going to do the same thing and we get 135 degrees.
01:33
So now we can find our yield strength...
