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. Webx ′ = centroidal axis. x = any axis parallel to the centroidal axis. I = moment of inertia about the x-axis. ˉI = centroidal moment of inertia. A = area of the section. d = distance between x and x’. In the same manner, the transfer formula for polar moment of inertia and the radii of gyration are respectively.
