Question

Perpendicular axes theorem and their applications ​

Answer 1

Answer:

Perpendicular Axis Theorem

Perpendicular Axis TheoremThis theorem is applicable only to the planar bodies. Bodies which are flat with very less or negligible thickness. ...

That means the moment of inertia about an axis which is perpendicular to its plane is equal to the sum of its moments of inertia about two perpendicular axes.

Explanation:

please thora to wait kro yaar.

make sure it's right.

Answer 2

Explanation:

Application of Perpendicular Axis Theorem

This theorem is most useful when considering a body which is symmetrical about two out of the three axes. If the value of the moment of Inertia about these two axes is known, then we can easily calculate the Moment of Inertia about the third axis by applying this theorem.
