![]() Learn how to calculate the centroid of a beam section. For non-symmetrical shapes (such as angle, Channel) these will be in different locations. For symmetrical shapes, this will be geometric center. Centroid (Cz, Cy)–this is the center of mass for the section and usually has a Z and Y component.See Moment of Ineria of a circle to learn more. Also worth noting that if a shape has the same dimensions in both directions (square, circular etc.) these values will be the same in both directions. ![]() This is because sections aren’t designed to take as much force about this axis Y- Axis (Iy) –This is about the Y axis and is considered the minor or weak axis.Z-Axis (Iz)–This is about the Z axis and is typically considered the major axis since it is usually the strongest direction of the member.The higher this number, the stronger the section. Moment of Inertia (Iz, Iy)–also known as second moment of area, is a calculation used to determine the strength of a member and it’s resistance against deflection.Area of Section (A) - Section area is a fairly simple calculation, but directly used in axial stress calculations (the more cross section area, the more axial strength).Here is a concise list of the section property terms and definitions: ![]() ![]() ![]() The moment of inertia calculator will accurately calculate a number of important section properties used in structural engineering. ![]()
