![]() ![]() How to calculate the properties of a circle sector? Moment Of Inertia Of A Circle Moment of inertia of a circle or the second-moment area of a circle is usually determined using the following expression I = π R 4 / 4 Here, R is the radius and the axis is passing through the centre. How is the moment of inertia of a circle determined? The second moment of area, also known as moment of inertia of plane area, area moment of inertia, polar moment of area or second area moment, is a geometrical property of an area which reflects how its points are distributed with regard to an arbitrary axis. What is the area moment of inertia filled circular sector?Īrea Moment of Inertia – Filled Circular Sector. ![]() Now if take a quarter circle, the moment of inertia relative to the x-axis and y-axis will be one quarter the moment inertia of a full circle.īy increasing the radius from the axis of rotation, the moment of inertia increases thus slowing down the speed of rotation. Moment Of Inertia Of Quarter Circle Derivation Notably, in a full circle, the moment of inertia relative to the x-axis is the same as the y-axis. What is the moment of inertia of a quarter circle?
