thanks for the help 256 bits.:smile:

Glad you pointed that out sir. Thanks:smile: Actually, I took the acceleration of block 1 as a1 and wrote the following equations (the same as my first post) : 1) a1+a2+a3=0 2) for block 1 : T = (-)*(a1) (notice the minus sign) 3) for block 2 : 2*g - T = 2*a2 4) for block 3 : 3*g - T =...

ok..thanks again!

Do you mean that we calculate torque using r x F definition and then dL/dt. But in general, they aren't equal. However, in the non-accelerating case, they are. I have Goldstien and feynman lectures. Thanks a lot for helping..:smile:

Thank you so much for the information sir. :smile: However, I have some doubts : 1)Why can't the condition of rotational equilibrium be applied about an accelerating point and how do we take moments about such points? 2)How does the special property of CM (i.e ζ = dL/dt) imply that the...

I had proved that tensions are equal and just stated the result on the forum. I think that's pretty trivial to see. Apologies for that. I have chosen the uppermost pulley as reference for displacements x1,x2 and x3. Now, the vector x1's tail is at this pulley and it points towards block 1...
