Question

Two point masses m1 and m2 are joined by a weightless rod of length r. Calculate the moment of inertia of the system about an axis passing through its centre of mass and perpendicular to the rod.

Open in App
Solution

r1=(m2m1+m2)r
r2=(m1m1+m2)r
Ic=m1r21+m2r22
l=μr2 where μ=m1m2m1+m2 is called the reduced mass of two masses.
