Q. A chain hangs on a thread and touches a surface of a table by its lower end. Show that after the thread has been burnt the force exerted on the table by the falling part of the chain at any moment is twice the weight of the part already resting on the table.

Q. A uniform chain of mass

M

L

is held vertically in such a way that its lower end just touches the horizontal floor. The chain is released from rest in this position. Any portion that strikes the floor comes to rest. Assuming the chain does not form a heap on the floor, calculate the force exerted by it on the floor when a length

x

has already reached and rest of the length l - x is in the air.

hangs from a thread and touches the surface of a table by its lower end. Find the force exerted by the chain on the surface when half of its length has fallen on the table. Assume that the fallen part does not form heap.

Q. A flexible chain of length 2m and mass 1 kg initially held in vertical position such that its lower end just touches a horizontal surfaces, is released from rest at time t=0, Assuming that any part of chain which strike the plane immediately comes to rest and that the portion of chain lying on horizontal surface does not form any heap, the height of its center of mass above surface at any instant

t = 1 / \sqrt{5}
