A heavy flexible uniform chain of length `pi r` and mass `lambda pi r` lies in a smooth semicircular tube AB of radius 'r'. Assuming a slight disturbane to start the chain in motion, find the velocity v with which it will emerge from the end of the tube?

A uniform chain of length of length pir lies inside a smooth semicircular tube (AB) of radius f. Assuming a slight disturbance to start the chain in motion, the velocity it will emerge from the end (B) of the tube will be

A uniform chain of length of length pir lies inside a smooth semicircular tube (AB) of radius f. Assuming a slight disturbance to start the chain in motion, the velocity it will emerge from the end (B) of the tube will be

A smooth semicircular tube AB of radius r is fixed in a vertical plane and contains a heavy flexible chain of length pir and weight Wpir as shown. Assuming a slight disturbance to start the chain in motion, the velocity v with it will emerge from the open end B of the tube is:

A uniform chain of length l and mass m lies on a smooth table. A very small part of this chain hangs from the table. It begins to fall under the weight of hanging part. Find the velocity of chain when the length of hanging part becomes y.

A chain of length l and mass m lies on the surface of a smooth sphere of radius R>l with one end tied to the top of the sphere.

A chain of length 1 and mass m lies on the surface of a smooth sphere of radius Rgt1 with one end tied to the top of the space. Find the gravitational energy of the chain with reference level at the centre of the sphere

A chain AB of length equal to the quarter of a circle of radius R is placed on a smooth hemisphere as shown in figure -3.66. When it is released, it starts falling. Find the velocity of the chain when it falls of the end B from the hemisphere.
