Sol: The given plate is symmetrical about the y-y axis, therefore \ = 150 mm. Second Moment of Area of Quarter-circle Second Moment about x by Double Integration Second Moment about y by Double Integration Polar Moment about O from. To find \, we have to divide the whole Figure into standard areas.Įxample: Find the moment of inertia of a plate with a circular hole about its centroidal x axis as shown in Fig.8. Sol: The given I-section is symmetrical about the y-y axis, therefore, Derivation (cont’d) onsider an axis ’ parallel to AA’ through the centroid C of the area, known as the centroidal axis. = Įxample: Determine the moment of inertia about the horizontal axis passing through the centroid of the section as shown in Fig.7.
