Explanation Given: R be the rectangle [ − a , a ] × [ b , − b ] with uniform density and total mass M. Formula used: Mass density δ = total mass/total area I x = ∬ R y 2 δ ( x , y ) d A I y = ∬ R x 2 δ ( x , y ) d A I o = I x + I y M = ∬ R δ ( x , y ) d A R x = I x M Where R x is the radius of gyration about x axis, I x is the moment of inertia about x axis and I o is the moment of inertia about origin. Calculation: Part a) Mass density δ = total mass/total area = M 4 ∫ 0 a ∫ 0 b 1 d y d x = M 4 ∫ 0 a [ y ] 0 b d x = M 4 b ∫ 0 a 1 d x = M 4 b [ x ] 0 a = M 4 a b For part b) I x = ∬ R y 2 δ ( x , y ) d A = 4 ∫ 0 a ∫ 0 b y 2 . M 4 a b d y d x = 4 M 4 a b ∫ 0 a [ y 3 3 ] 0 b d x = M 3 a b ∫ 0 a [ y 3 ] 0 b d x = M b 3 3 a b ∫ 0 a 1 d x = M b 3 3 a b [ x ] 0 a = M a b 3 3 a b = M b 2 3 I y = ∬ R x 2 δ ( x , y ) d A = 4 ∫ 0 a ∫ 0 b x 2 ...
