A metre rule, weighing 100 g rests on a tyable with a part projecting over the edge. Find the length of the part projecting out if a 5 g body hung at the end just tills the rule.

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 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 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 ?

The diagram alongside shows a uniform metre rule of weight 100 gf being balanced on a knife edge placed at the 40 cm mark, by suspending a weight w gf at the mark 20 cm, find: the position of another weight of 50 gf to balance the rule in part (ii).
