SoluTion :
✴ Given :-
▪ Radius of outer ring = 3R
▪ Radius of inner disc = 2R
▪ Angular velocity of ring = ω(Clockwise)
▪ Angular velocity of disc = ω/2
(Anti-clocewise)
▪ Distance between centre and P point = R
▪ OP makes angle 30° with horizontal
✴ To Find :-
▪ Linear velocity of P point...
✴ Diagram :-
▪ Please see the attached image for better understanding.
✴ Calculation :-
✒ Since, outer ring is rolling without slipping, the point on the ring in contact with the ground (A) is at rest,
- i.e. = 0
✒ Thus, velocity of the point O is given by
✒ The point P lies on the inner disc having an angular velocity
✒ The position vector from O to P is
✒ Thus, velocity of the point P is given by
