In this question, we have to calculate the moment of inertia in pre -tech in the first part.
00:05
Now, first we have to write ix is equals to ix1 plus ix2 plus ix3 minus ix4 as the cubic.
00:23
Graph we have by triangle.
00:25
So the ix1 is equals to ic1 plus ic4.
00:35
It's probably equals to, now we have to put the value over here which is 6 multiplied by 8 cube upon 3 square 1 upon 2 multiplied by 6 multiplied by 9.
00:50
2 multiplied by 9 by 3 whole cube.
00:55
And then this will be equals to 121 .5 plus 9 .12 and ix1 is equals to 1093 .5.
01:14
Now, in this we have to find the ix2 value.
01:19
Then ix2 value is equals to ic1 plus ic4.
01:25
Now we have to put the value over here.
01:29
And after that we get 108 plus 324.
01:34
And in this 324 in the next we have to solve the whole equation and we get 432 ix to power 4...
