Question

for a disc of given density and thickness ,its moments of inertia varies with radius of the disc as?​

Answer 1

Answer:

Explanation:

Moment of inertia of disc is directly perpotional to r^4 .

Answer 2

Answer:

MOI=M$R^{2}$

mass=density x area X thickness =ρπ$R^{2}$                                                                  MOI=M$R^{4}$ρπ.                

so MOI is directly proportionate to $R^{4}$
