how do we calculate the moment of inertia of a solid cone?
Hi Deepak,
Divide the Cone into Infinitesimal Discs as shown in the figure
Now calculate the Moment of Inertia of this disc using sdn as the nass and a proportional radius of t6his disc of infinitesimal thickness found using similar triangles
Then integrate using
the following formula
I = ∫r2dm
In this case r would be varying and so you have to determine dm in terms of r and dr
Then integrate over the whole cone
Regards
