Calculate the moment of inertia of the egg having a mass of 7 kg and radius of 44 cm.(a) .968 kgm^2(b) 1.454 kgm^2(c) 1.545 kgm^2(d) 1.552 kgm^2The question was posed to me in final exam.This intriguing question originated from Dynamics topic in chapter Dynamics of Electrical Drives of Electric Drives

Answer»

The CORRECT choice is (d) 1.552 kgm^2

The best I can explain: The moment of inertia of the egg can be calculated USING the formula I=∑miri^2. The mass of egg and RADIUS is GIVEN. I=(7)×(.44)^2=1.552 kgm^2. It depends upon the ORIENTATION of the rotational axis.
