- Question
The ratio of the moment of inertia of a circular plate and that of a square plate for equal depth, is
Options- A. less than one
- B. equal to one
- C. more than one
- D. equal to 3?/16
- E. none of these.
- Correct Answer
- equal to 3?/16
ExplanationFor circular plate, MI = ?*d^4/64.For square plate, MI = d^4/12.
So, Ratio = MI of circular plate/MI of square plate.
= 3*?/16.
