Step 2] Find … WebThe second moment of area in the y-direction can be found by letting. F = [ 0 ( y − cy)3 3] The product moment of area can be found by letting. F = [ x2 ( y − 2cy) + 2cxcyx 4 y2 ( x − 2cx) + 2cxcyy 4] The normal can be found using the cross-product between the normalized side direction vector and a vector pointing out of the plain.
