Moment of Inertia of Circle
The moment of inertia of circle is also referred the second-moment area of a circle. This calculates the Area Moment of Inertia of a semi-circle about various axes.

The polar moment of inertia of circle is used for the analysis of objects with circular profiles subjected to the torsional or twisting load.
. Moment of Inertia is an important geometric property used in structural engineering as it is directly related to the amount of material strength your section has. Easily calculate the second moment of inertia of square rectangle circle triangle and many other geometric shapes using this moment of inertia. In case of any hurdle try using the area moment of inertia calculator for accurate and instant outputs of various parameters that are related to the moment of inertia.
I z t f w 3 12 h t w 3 12. I z 4177 10 5 m m 4. The moment of inertia is that property of an object which opposes the change of state of the object in rotational motion.
The moment of inertia of the semicircle is generally expressed as I πr4 4 The role that the mass plays in the translation motion is played by the moment of inertia in the rotational motion. The moment of inertia or more accurately the second moment of area is defined as the integral over the area of a 2D shape of the squared distance from an axis. Radius and elevation of the semi-circle can be changed with the blue point.
The inertia of an object depends only on its mass. Now using the perpendicular axis theorem the inertia of circle along the Z-axis that is. As both x and y axes pass through the centroid of the circular area Equations 88a and 88b give the moment of inertia of circle about its centroidal axes.
The moment of inertia of an object is a determined measurement for a rigid body rotating around a fixed axis. If you are new to structural design then check out our design. The above concept can be.
