    It's a matter of depression that we would never be getting this old Alakh Sir as our teacher!
    Can't find this caring teacher with childish attitude and energetic behaviour within todays PW!!!!
    His laugh has changed from having purity and true joy to fake pressurized consecutive flow of sounds!
    I still force myself to watch PW series because of those unforgettable glimpses of yesteryears when he taught us with no smart board no stylus no high quality camera,yet having pure love and care!
    Alright let's not regret how he has changed through times as changing is within the characteristics of human!

    the sum at 40:53 can also be solved by considering the joint between 2 rods as centre of mass as both the rods have same mass and length and considering both the bodies as a single body.the axis passing through the com will have and inertia as 2[ml^2/3] as the centre of mass if the edge of 2 rods . and then by using parallel axis theorem we get 5ml^2/3.that would be much easier
