MOMENTO DE INERCIA
CABEZAS ALEX – S2 P3
Demostrar que el momento de inercia de un disco delgado
es:
Sabemos que:
𝐼𝑚𝑎𝑠𝑎 = 𝑟2
𝑑𝑚
Además de ello se observa que:
𝑑𝑚 = 𝜌𝑡 𝑑𝐴
Entonces:
𝐼𝑚𝑎𝑠𝑎 = 𝜌𝑡 𝑟2
𝑑𝐴
r es la distancia desde un eje

Para el eje x:
Dado a que es perpendicular al plano, se procede a utilizar el
momento polar de inercia
𝐼𝑚𝑎𝑠𝑎,𝑋 = 𝐼𝑚𝑎𝑠𝑎,𝑌 + 𝐼𝑚𝑎𝑠𝑎,𝑍 = 2 𝐼𝑚𝑎𝑠𝑎,𝑌
