hey, I want to ask you something about to calculate the moment of inertia for any shape. My problem is that I can not calculate that moment of inertia values for any shape. Such as rectangle or stick and the others. I have tried to calculate for stick and I have found the solution of Ix=∫y2.dm is ∫(L/2)^2dm and after that point how can i calculate dm for this integrnt. I wrote insted of dm which is dm=M/L.dL but I cannot forward within the equation.. ı think there is a very simple thing in this equation but I cannot see that and I cannot solve thıs equatıon properly. I fell like a blind for that. Please if you help me clarify for that solving i would be appreciate for taht.
