Moment of inertia of a semi circular wire of mass m?
If we are considering the semi circular wire of mass m to have a relatively small cross sectional radius, r compared to radius of the semi circular arc, R And that we are considering the semi circular wire to lie in a xy plane. The mass moment of inertia taken about the z-axis (perpendicular to the plane) located at the cg position will be. Izz=m*(R^2)*(PI-(4/PI))/PI I did a check of this calculation with the way Catia calculated the same property. And the difference was found to be 0.03% When using the following geometry. density=0.000001kgmm^3 Semi circular wire Radius R =60mm cross sectional radius of wire = 1mm results from Catia V=592.176mm^3 m=0.000592176kg Izz=1.268159kgmm^2 hand calculated results V=592.176mm^3 m=0.000592176kg Izz=1.267835kgmm^2 % difference [((1.268159)-(1.267835))/(1.267835)]*100=0.03% Please carry out a check on the Izz calc. I determined it from 1st principles, so I may of made a mistake

Why does the coasting rotating system slow as water drips into the beaker?
Ans : By the formula of moment of inertia , I=mr2 (2=square) As by the formula it is clear that the moment of inertia depends on the mass and the radius of a particular body , so as the mass increases moment of inertia will considerably increase , So as the water drips into the beaker the mass of the beaker will increase By the law of conservation of angular momentum Moment of inertia is inversely proportional to the angular velocity ( omega ) , Since in the above case of coasting rotating system moment of inertia is increased so the angular velocity (omega) will also decrease and hence the coasting rotating system will now rotate slowly as compared to its rotation before dripping water !
