Solid Rectangular Cross Section The Area Moment of Ineria for a rectangular section can be calculated as Ix = b h3/ 12 (3) where b = width h = height Iy = b3 h / 12 (3b) . Solid Circular Cross Section The Area Moment of Inertia for a solid cylindrical section can be calculated...
Moment of Inertia refers to the property of an object in angular motion that is analogous to mass in translational motion. It is calculated as the sum of the moments of inertia of the mass elements in the body, where each element of mass is located at a different distance from the center...
· For Square Cross-Section: For a square, the moment of inertia equation is Ix=Iy= a4/12 where a=length of side. · The equation for Moment of Inertia for Circular Cross-Section: I=πd4/64, where d=circle diameter, is the moment of inertia for a circular cross-section. A pipe...
The elongated tubular member has a gradually diminishing cross-sectional moment of inertia so that the drill string within the tubular member is constrained to bend in a substantially circular arc of large radius. In its more rigid portion, the elongated member has a gradually tapering wall ...
This property is useful in understanding the stiffness of a cross section when bent. It can be seen that placing a good deal of the cross-sectional material away from the centroid—as in the I-shaped section or, to a lesser extent, in the circular ring—increases the moment of inertia, ...

The pipe bends are manufactured from the pipe bending process, and during the process, the circular cross-section is deformed into noncircular cross-section. The cross-section difference affects the collapse moment due to a change in moment of inertia of the pipe bend about its axis of rotation...
