We'd like to determine the max stress in the wood as well as the steel.
00:07
Okay, so let's find our centroids for our problem.
00:17
So, beginning, we have our ew equal to 12 gpa given in our problem.
00:26
E .s is 200 gpa.
00:30
Our area 1 is 37500 millimeter squared, and area 217 ,17 .7 .7 .7 .1.
00:39
D millimeter squared.
00:43
Now, end of water, or end of wood is equal to 1, and end of steel is 16 .67.
00:50
So let's look for our centroid of our compound section.
00:54
Y is going to be equal to our area 1 times y1 plus a2, over a1 plus a2...
