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 =...
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...
