1

If I is the moment of inertia of a solid body having alpha coefficient of linear expansion then the change in I corresponding to a small change in tempt delta T is

2

Solution is aatched . There is a condition if the axis is placed parallel to body then no change in MOI. But MOI will change if axis of rotation is placed perpendicular to body.
