Question

Moment of inertia problem involving finding a new one by attaching a mass to an object with a known moment of inertia.

Answer 1

A square of mass m and length L rotating about it's center has a moment of inertia of\[I=\frac{1}{6}mL^2\]If a point mass M is attached to a corner of the square, what is it's new moment of inertia?

Answer 2

i went with\[I=I_{com}+Md^2\]\[I=\frac{1}{6}mL^2+\frac{1}{2}ML^2\]
