(PC-PI / 2018) Para determinar o momento de inércia da área composta em relação ao eixo x da figura abaixo, escolha a opção CORRETA. A I x = ( 1 / 3 ⋅ 300 3 ⋅ 200 ) + [ 1 / 4 ⋅ π ⋅ ( 75 ) 4 + π ⋅ ( 75 ) 2 ⋅ ( 100 ) 2 ] ???? ???? = ( 1 / 3 · 300 3 · 200 ) + [ 1 / 4 · π · ( 75 ) 4 + π · ( 75 ) 2 · ( 100 ) 2 ] B I x = ( 1 / 3 ⋅ 300 ⋅ 200 3 ) + [ 1 / 4 ⋅ π ⋅ ( 75 ) 4 + π ⋅ ( 75 ) 2 ⋅ ( 100 ) 2 ] ???? ???? = ( 1 / 3 · 300 · 200 3 ) + [ 1 / 4 · π · ( 75 ) 4 + π · ( 75 ) 2 · ( 100 ) 2 ] C I x = ( 1 / 3 ⋅ 300 ⋅ 200 3 ) − [ 1 / 4 ⋅ π ⋅ ( 75 ) 4 + π ⋅ ( 75 ) 2 ⋅ ( 100 ) 2 ] ???? ???? = ( 1 / 3 · 300 · 200 3 ) − [ 1 / 4 · π · ( 75 ) 4 + π · ( 75 ) 2 · ( 100 ) 2 ] D I x = ( 1 / 3 ⋅ 300 3 ⋅ 200 ) − [ 1 / 4 ⋅ π ⋅ ( 75 ) 4 + π ⋅ ( 75 ) 2 ⋅ ( 100 ) 2 ] ???? ???? = ( 1 / 3 · 300 3 · 200 ) − [ 1 / 4 · π · ( 75 ) 4 + π · ( 75 ) 2 · ( 100 ) 2 ] E I x = ( 1 / 3 ⋅ 300 3 ⋅ 200 ) − [ 1 / 4 ⋅ π ⋅ ( 75 ) 4 ] ???? ???? = ( 1 / 3 · 300 3 · 200 ) − [ 1 / 4 · π · ( 75 ) 4 ]
