Spring-Pulley System

Does any body know the "Extra Force Method" to solve the spring pulley system.
And also I want to know if there is any other method to solve pulley problems(system containing a no of pulleys).
if yes then plz tell me.....

I dont know and have never heard of this.. (is it a name to somethign every commonly known?) That is what a lot of teachers do these days :D

Neways one method is work done by internal forces.. *tension generally..

bhaiyya using tension is da usual method.... but for a system containing a mass and four to five pulleys and an equal no of spring... it becomes quiet lengthy.... so i wanted to know a shorter method for these types of problems....

I think Rajat means that the motion of the pulley
would be due to the extra weight (m2-m1) which gives
the extra force.
I just heard this once somewhere; have no idea if there is some another method

This is not the extra force method what iota.1 said
I at last got it from one of my friend today

In this we folly 3 steps

1.First assume the body is already in equlibrium

2.Elongate one spring at a time and find it effect on the objects displacement.

3.Find the relation between the displacement of the object and the displacement of the spring.
