We have the following system in ideal condition (pulleys and rope are mass-less and frictionless)
We need to find the conditions in which M3 will go downwards...
Ok so here's what I did:
M3g > T
And this is what I'm not sure of:
T=(M1g + 0.5M2g + M3g)/3
So the answer which I came to was:
2M3 > M1 + 0.5M2
But I'm a bit unsure, did I go wrong? how do I approach this question and how do I calculate the tension in the rope?
