Homework Statement
There is the moment of inertia about an x and a y-axis named, I_{x}, I_{y}. Then there is the moment of inertia about the centroidal x and y-axis named, \overline{I}_{x}, \overline{I}_{y}. Often we can look up these values in a table (like the figure included) and apply another idea called the parallel-axis therom to find moments about different axes. My question is: What is I_{y} and \overline{I}_{y} for the triangle? It seems to be missing from the picture. This also could illustrate my lack of understanding about what a moment of inertia really is.
Homework Equations
I = \overline{I} + A*d^{2}
where, A is the area and d is the distance between parallel axes.
