At the centroidal axis, the first moment of area of the object becomes zero. The first moment of area is the product of the area of the shape and the distance between the centroid of the shape and the reference axis. Q = A××𝓧 The centroidal axis passes through the centroid of the shape. ∴ 𝓧 = 0 Therefore … See more First moment of area about any reference axis is the product of the area of shape and distance between the centroid of shape and the … See more The first moment of area is used for the following purpose:- 1] To find the centroid of complex shapes:- For the complex shape consisting of different simple geometric shapes, … See more Following are the steps to calculate the first moment of area of complex shapes:- Step 1]Divide the complex shape into simple geometric … See more The first moment of area for circle, hollow circle, and rectangle shape is given below:- The below figure shows the circle with the centroid located at a distance of (x, y) from the origin of the axis. For the above circle, the first … See more WebMay 2, 2024 · The moment of inertia relative to centroidal axis x-x, can be found by application of the Parallel Axes Theorem (see below). The position of the centroid must be determined first though, and more specifically its vertical distance from the bottom base (in other words its y 0 coordinate). how to download and save youtube videos
