Question

Flat disk of radius R has circular hole of radius R/2 that is positioned as shown on the picture. Mass of the disk is m. Find moment of inertia I of such disk with respect to the axis going through the geometrical center of the disk O perpendicular to the disk’s plane

Answer 1

For us to get the moment of inertia, we have to calculate it with the radius R, and then we will subtract the moment of inertia to the R/2 disc with the axis of it that will be found in the circumference.
