1.	Calculate the moment of inertia of the disc having a mass of 4 kg and diameter of 1458 cm.(a) 106.288 kgm^2(b) 104.589 kgm^2(c) 105.487 kgm^2(d) 107.018 kgm^2I had been asked this question in an interview.I'm obligated to ask this question of Methods of Starting Electric Motors topic in division Starting of Electric Drives
Answer» The correct OPTION is (a) 106.288 kgm^2 The BEST explanation: The moment of inertia of the disc can be calculated using the formula I=mr^2×.5. The mass of the disc and diameter is GIVEN. I=(4)×.5×(7.29)^2=106.288 kgm^2. It depends upon the ORIENTATION of the rotational AXIS.
