WebApr 8, 2024 · From this value, the moment of inertia of the area can be calculated on 0 to 'a' as: A = ∫ 0 a ∫ 0 2 π λ r d θ A = π a b. Next, to find out the moment of inertia, the formula will be given by: I = ρ ∫ ( X 2 + Y 2) d A. From which we can get the following: I = ρ λ a b 4 ( a 2 + b 2) = M ( a 2 + b 2) 4.
