Statement

$2.8.43.$ The ant decided to drag a straw to the anthill. What should he do if the force with which he can pull the straw is somewhat less than the maximum frictional force at rest?

Solution

The ant should lift the straw from the ends alternatively turning it through a certain angle while doing so.In this way it can move the straw without actually needing to drag it and thus would be able to bypass the frictional force. We must note that the angle through which the straw has been turned through in the air must be less than 360 degrees otherwise lifting and turning the straw would be of no use.

Answer

The ant should lift the straw from alternate ends and turn it through a certain angle in the air continuing the process until it reaches the anthill.
