Learning Goal: To be able to calculate the moment of inertia of composite areas An object's moment of inertia is calculated analytically via Integration, which involves dividing the object's aren into the elemental strips that are parallel to the axes and then performing the integration of the strip's moment of inertia correct The parallel-axis theorem is used in the calculation of the moment of inertia for composite areas. Here, the reference axis coincides with the rectangle's base and semicircle's diameter....
Moments of Inertia for Composite Areas Item 1 Because the principle of superposition applies to moments of inertia, we are free to section a shape in any way we like provided no part of the shape is left out or contained in more than one section. The original shape could have been sectioned in the following manner Part A-Moment of Inertia of a Composite Beam about the x axis ▼ For the built-up beam shown below, calculate the moment of...
