In this question, we are going to calculate the moment of inertia of the given shape.
00:04
So they have given the shape here.
00:06
We split into the four segment, so which is triangle and rectangle, quarter circle.
00:13
So this is the rectangle shape.
00:15
This is the second rectangle.
00:17
This is triangle and quarter circle.
00:19
So we have to cooperate the moment of inertia of separately and then find the moment of the shape of the whole shape.
00:27
So we take it here, rectangle first.
00:30
First rectangle we take it this is a 4 inch and this is 10 because a and b we have add here 6 and 4 we get 10 so this length is 10 so find it which is for first rectangle rectangle so using that a which is equal to 4 times 10 which is 40 in squared and then y 1 we can take it that is 10 that is 10.
01:11
Divided by 2 which is equal to 5 inch 1 minute of energy x1 which is 4 times 10 cube divided by 12 we can write it here and we can simplify this get 333 .33 inch power 4 so this is the first second rectangle we can take it and we can get it a value which is for second rectangle, i, x2, which is 90 inch power 4...
