An object is formed by attaching a uniform, thin rod with a mass of m = 7.07 kg and length L = 5.16 m to a uniform sphere with mass M = 35.35 kg and radius R = 1.29 m. What is the moment of inertia of the object about an axis at the right edge of the sphere?
I think the expression would be 0.4MR^2+MR^2+mL^/3, is it?
Compare the three moments of inertia calculated above:
I,CM < I,left < I,right
I,CM < I,right < I,left
I,right < I,CM < I,left
I,CM < I,left = I,right
I,right = I,CM < I,left
how can I calculate the moment of inertia of the object about an axis at the center of mass of the object?
