Question

What is the first moment of area about a centroidal axis?

Answer 1

Hope it helps . It's a good question that you asked

Answer 2

The first moment of area about a centroidal axis is zero.

• Because the centroid lies on the centroidal axis, the perpendicular distance between the centroid and the axis must likewise be zero.
• Any line that goes through the mid-centroid section is known as the centroidal axis.
• There could be an unlimited number of lines that go through the point of gravity's center.
