Homework Statement
I'm supposed to solve for the maximum moment assuming the beam bends about the y-axis (not the z axis as shown in the image. Same image for different questions). I don't understand how to find the moment of inertia in this case. The solution gives the moment of inertia for the 80 x 16 mm part of the bar to be
[tex] I =\frac{1}{12}(80)(16^3) + 80(16)(16^3)[/tex]
What I don't understand is where the 80(16)(163) comes from. Can some one explain?
