    2. sir pls can you tell at 5:36 why will the axis of rotation apply some force on disc pls tell sir

    3. sir the torque acting is zero as the com is not moving (as it is at rest) and all forces act through centre of mass so the hinge force balances the friction force overall. CAN YOU PLEASE TELL ME IF I AM RIGHT OR WRONG.and if wrong please give me the explantion for troque being zero

    4. Sir how have you considered friction as internal force and how angular momentum is conserved?

    5. Sir, In case 4 i.e. Angular momentum of a rotating body about an AOR passing through COM and moving translationally. L(C) was around AOR, so how can this be taken same around point P. As if we take Velocity to be zero in final expression it will suggest L (P)=IW. Please explain.

    6. sir can we say that since axis of rotation and mg (force exerted by the block) are parallel therefore net torque by the block becomes zero because sin (theta) becomes zero so angular momentum can be conserved about the axis of rotation

    Ans 1 ->
    therefore angular momentum can be conserved about that axis
