1.Rotational Dynamics

A bucket containing water is revolved in a vertical circle of radius r . To Prevent the water from falling down, the minimum frequency of revolution required is

1.Rotational Dynamics

A body moving in a circular path with a constant speed has constant

1.Rotational Dynamics

A round disc of moment of inertia I_2 about its axis perpendicular to its plane and passing through its centre is placed over another disc of moment of inertia I_1 rotating with an angular velocity ω about the same axis. The final angular velocity of the combination of discs is

1.Rotational Dynamics

Angular momentum is conserved

1.Rotational Dynamics

A rod of length L and Mass M is bent to form a semicircular ring, as shown. The moment of inertia about XY is

1.Rotational Dynamics

Two discs of same material and thickness have radii 02 m and 0.6 m. Their moments of inertia about their axis will be in the ratio

1.Rotational Dynamics

4 thin rods of same mass M and same length L form a square, as shown in the figure. Moment of inertia of this system about an axis through Centre O and perpendicular to its plane is

1.Rotational Dynamics

Three rods each of length l and mass M are placed along the X, Y and Z axes in such a way that one end of each rod is at the origin. The moment of inertia of the system about axis is

1.Rotational Dynamics

Two spheres each of mass M and radius R / 2 are connected with a massless rod of length 2 R as shown in the figure. What will be the moment of inertia of the system about an axis passing through the centre of one of the spheres and perpendicular to the rod

1.Rotational Dynamics

Two particles of masses, M1 and M2 are connected by a rigid massless rod of length R to constitute a dumbbell, which is free to move in the plane. The moment of inertia of the dumbbell about an axis perpendicular to the plane passing through the centre of mass is
