I want to be tought on algorithm of constraint ( newton's LOM )
Rates assured !

In pulley problems..you can use the t.v method.. i.e. The total work done by internal forces is zero..hence you can get the relation between the displacements and differentiating it you get the relations btwn velocities..

no.
I want to learn as :

1. indentify the ropes
2. identify each segment of a rope.
3. for the polleys, blocks, etc fixed at thje ends of the ropes, assign arbitrary acceln in preferably same direction
4. if the distance detween the segments of the strings appear to increase, find the relative acceln between the two ends and assign it + sign, else -sign
5. each string will give a single equation whose solution provides the constraint relation

it is not important where u stand, but in which direction u are moving |

IS THE PRINT OF ALL YEAR OF SOME BOOKS (LIKE HC VERMA ,HALLIDAY, MORRINSON,AGGARWAL, RC MUKHERJEE,HALL NIGHT,IRODOV,BARMAN,TMH,AND MANY MORE SUCH BOOKS NEEDED FOR IIT )BE SAME
I MEAN WILL THE 1993 EDITION AND 2008 EDITION BE SAME WITHOUT ANY CHANGE IN SINGLE WORD
SORRRRRRRYYYYYYYYY TO DO THIS HERE
BUT I AM IN UTTER NEED OF KNOWING THIS

use this simple formula for constraints...
 foa the whole system where a= acceleration, velocity oir displacement and * stands for DOT PRODUCT meaning a cos x term will also appear where x is angle between a and T and T is tension of all strings and their resp acc, vel, displacement is a... this is VERY rare formula derived using work energy and calculus. can be used everywhere... enjoy and plzzz rate.
