Two point masses are joined by a rigid weightless rod of lenght "l", the centre of which is constrained to move on a circle of radius 'a'. Set up the kinetic energy in(adsbygoogle = window.adsbygoogle || []).push({}); generalisedcoordinates.

So in this case, since the 2 mass m are joined by a rod, I consider the reduced mass of the system [itex]\mu[/itex]:

[tex]{1\over {\mu}} = {1\over m} + {1\over m}[/tex]

[tex]\mu = {m\over 2}[/tex]

Am I going right? How do I set up the KE in this case?
