A uniform square plate is folded from one of its corner as shown in figure. The moment of inertia about the xx' axis is then (xx' axis is perpendicular to plane of square plate and passes through centre)
Options:
Answer:
C
Solution:
Folding only relocates an element by rotation about the fold.
For the stated perpendicular axis, the folded triangular part moves closer to the axis; therefore the moment of inertia decreases.
