Moment of inertia of a circular section can be calculated by using either radius or diameter of a circular section around centroidal x-axis or y-axis. Example Find the moment of inertia of a circular section whose radius is 8” and …
Moment of inertia is the product of first moment of area and the centroidal distance of the area from a given axis. If A.x is the first moment of area of certain section then (Ax).x is the moment of inertia (second …
Centroid of I-section can be found easily with respect to reference x-axis because of section symmetry around y-axis. As shown in the example below; Example Find the centroid of I-section given below. Solution Step: 1 First divide the whole section into …
Centroid of T-section can be found easily with respect to reference x-axis. This is so because T section is symmetrical about Y-axis. Centroid of T Section Example Find the centroid of T-section as shown below. All units are in cm. …
