Can you derive it?hutchphd said:I think they are assuming the material has uniform mass density. So the mass is proportional to the area but then they are off by factor of 2.
For polar area moment of inertia, yes, but for Ix , or Iy, the approximation should be as given.hutchphd said:but then they are off by factor of 2.

The Tubular Column Moment of Inertia is a measure of an object's resistance to changes in rotation. It is calculated by multiplying the mass of the object by the square of its distance from the axis of rotation.
The Tubular Column Moment of Inertia takes into account the hollow space inside the column, while the Moment of Inertia of a solid cylinder only considers the mass and shape of the outer surface. This makes the Tubular Column Moment of Inertia a more accurate representation of the object's resistance to rotation.
The Tubular Column Moment of Inertia is an important factor in determining the stability and strength of a structure. It helps engineers design structures that can withstand external forces and maintain their shape and stability.
The Tubular Column Moment of Inertia can be calculated using the formula I = mr², where I is the moment of inertia, m is the mass of the object, and r is the distance from the axis of rotation. This formula can be applied to different cross-sectional shapes, such as circles, rectangles, and triangles, to determine the moment of inertia.
Yes, the Tubular Column Moment of Inertia can be changed by altering the mass or shape of the object. For example, increasing the thickness of the tube or adding internal supports can increase the moment of inertia, making the object more resistant to rotation. However, changing the moment of inertia may also affect the overall stability and strength of the structure.
