A rectangular brick is kept on a table with a part of its length projecting out. It remains at rest if thelength projected is slightly less than half the total length but it falls down if the length projected is slightly more than half the total length. Give reason.

A unifrom heavy chain is placed on a table with a part of it hanging over the edge. It just begins to slide when this part is one-third of its length. The coefficient of friction between the table and the chain is

A uniform meter scale of mass 1kg is placed on table such that a part of the scale is beyond the edge. If a body of mass 0.25kg is hung at the end of the scale then the minimum length of scale that sould lie on the table so that it does not tilt is

A uniform rope of length l and mass m lies on a smooth horizontal table with its length perpendicular to the edge of the table and a small part of the rope having over the edge. The rope starts sliding from rest under the weight of the over hanging end. The velocity of the rope when the length of the hanging part is . x

A uniform chain has a mass m and length l . It is held on a frictionless table with one - sixth of its length hanging over the edge. The work done in just pulling the hanging part back on the table is :

A carpet of unit mass an unit length is laid on the floor. One end of the carpet is bent back and then pulled backwards with constants. Unit velocity, just above the part of the carpet which is still at rest on the floor. Find the speed of the centre of mass of the moving part. What is the minimum force needed to pull the moving part ?

A chain of mass m=0.80kg and length l=1.5m rests on a rough-surfaced table so that one of its ends hangs over the edge. The chain starts sliding off the table all by itself provided the overhanging part equals eta=1//3 of the chain length. What will be the total work performed by the friction forces acting on the chain by the moment it slides completely off the table?
