Calculate the moment of inertia of the rod about its center having a m

1.	Calculate the moment of inertia of the rod about its center having a mass of 11 kg and length of 29 cm.(a) .091 kgm^2(b) .072 kgm^2(c) .076 kgm^2(d) .077 kgm^2I had been asked this question during a job interview.I'm obligated to ask this question of DC Motors topic in section Characteristics of DC & AC Motors of Electric Drives
Answer» The correct choice is (d) .077 kgm^2 The explanation: The moment of inertia of the ROD about its center can be CALCULATED using the FORMULA I=ML^2÷12. The mass of the rod about its center and length is given. I=(11)×.0833×(.29)^2=.077 kgm^2. It depends upon the orientation of the rotational axis.
