dev bhatnagar · Answer

This a simple conceptual question I think following can help you

Mass of semicircular disc = M

Suppose there is a circular disc of mass 2M, then

Moment of intertia of circular disc = 1/2(2M)R²

Moment of intertia of circular disc = 1/2(2M)R2 = MR²

=> So, Moment of intertia of semi-circular disc = (1/2)MR²

sowmya thandra · Answer

can i get to know the detail information abt calculating moment of inertia

Tripti Arora · Answer

The above answer is right but from wrong method because moment of inertia is same for any arc or any part of disc it is not that if disc is half then mass is also half and Moi also half

parth · Answer

As it is uniform the mass didtribution is same all over the disc so half of the disc results in ½ of mass m=density(d)*vol M 1 =d*t* R 2 M 2=d*t* (r/2) 2
