A disc of mass `M` and radius `R` can rotate freely in a vertical plane about a horizontal axis at `O` distance `r` from the centre of the disc as shown in Fig. The disc is released from rest in the shown position. Answer the following questions based on the above information

Reaction force exerted by the hinge on the disc at this instant is

A disc of mass M and radius R can rotate freely in a vertical plane about a horizontal axis at O distance r from the centre of the disc as shown in Fig. The disc is released from rest in the shown position. Answer the following questions based on the above information The angular velocity of the disc in the above described case is

A uniform disc of mass M and radius R is pivoted about the horizontal axis through its centre C A point mass m is glued to the disc at its rim, as shown in figure. If the system is released from rest, find the angular velocity of the disc when m reaches the bottom point B.

A uniform disc of mass M and radius R is pivoted about the horizontal axis through its centre C A point mass m is glued to the disc at its rim, as shown in figure. If the system is released from rest, find the angular velocity of the disc when m reaches the bottom point B.

A disc of mass M and radius R is rolling with angular speed w on horizontal plane as shown. The magnitude of angular momentum of the disc about the origin O is :

A uniform circular disc has radius R and mass m . A particle, also of mass m , if fixed at a point A on the edge of the disc as shown in the figure. The disc can rotate freely about a horizontal chord PQ that is at a distance R//4 from the centre C of the disc. The line AC is perpendicular to PQ . Initially the disc is held vertical with the point A at its highest position. it is then allowed to fall, so that it starts rotation about PQ. Find the linear speed of the particle as it reaches its lowest position.
