Find out the moment of inertia of an annular area:
Find out the M. I. of an annular area among two circles where difference of radius is quite small, around any centroidal axis.
Solution
The centroid G of such a thin circular strip of small thickness t is at its geometrical centre as illustrated in Figure
Figure 4.36
We have, dA = ds × t
where ds = Arc length = a × d θ
Letting the plane of the area in XOY plane (O and G coincide),
= 2 π a3 × t
= 2 π at × a 2
= (Area of annular strip) × a 2
= A′ a 2
As the annular strip of area A′ is also axis symmetric, then I x = I y ,
Hence, we have I x = I y = I z /2 = A′ a2/2
