moment of area or moment of area, application and example. We will also derive
the formula for it.
First Moment of Area
the distance of C.G. of the area from the axis OY and y is the distance of C.G.
of the area from the axis OX.
This equation (1) is known as the first
moment of area about the axis OY
moment of area about the axis OX.
First moment of area/moment of area:
about an axis is defined as the product of area of the lamina and the
perpendicular distance of the C.G. of the area form the axis.
gravity of area.
area 10 cm2 and the distance of its C.G from the axis are shown in
the figure given below.
10 x 5 = 50
10 x 7 = 70
