Web2 mei 2024 · The moment of inertia relative to centroidal axis x-x, can be found by application of the Parallel Axes Theorem (see below). The position of the centroid must be determined first though, and more specifically its vertical distance from the bottom base (in other words its y 0 coordinate). This in turn, can be calculated using the first moments … WebThe moment of inertia can be calculated by hand for the most common shapes: Rectangle: (bh^3)/12. >Circle: (pi * r^4)/4. Triangle: (bh^3)/12. If the shape is more complex then the moment of inertia can be calculated using the parallel axis thereom. The parallel axis thereom is used to seperate the shape into a number of simpler shapes.
