Hi, in this question we have to first determine the area and the centroid.
00:06
So here for first segment, so for first segment we have, so this is the segment 1 and this is the segment 2.
00:14
Now we have to calculate the area and the centroid.
00:18
So a1 will be equal to, so a1 is 50 into 200 which is equal to 10 ,000 millimeter square.
00:26
So 10 ,000 millimeter square and we have centroid z bar is equal to, it is minus 25 millimeter and a into z bar is, so a1 into z1 bar is minus 25 into 10 power 4 millimeter cube.
00:44
Then for segment 2 we have 100, so a2 will be equal to 100 into 50, so 50 which is equal to 5000 millimeter square and we have z2 bar is the centroid for this section 2 which is equal to 50 and a2 into z2 bar is equal to, so 5000 into 50 that is 25 into 10 power 4 millimeter cube.

So these are the area and centroid...
