- Homework Statement
- I don't understand why is the soultion on 4th and last picture the way it is

- Relevant Equations
- F=ma

I don't get how is the 4th case different from the 1st case? In both cases the weights are hanging and are not accelerating, but somehow in 4th case the force meter shows 0N while in 1st shows 10N.

All other meters show 10N but the last one.

Now, I don't know hot to solve last one. I tried treating it like pulley problem with two weights. Tried to calculate the acceleration, a=((M-m)/(M+m))*g, and then M(4kg)*a(6)=F=24N. But, it's not, apparently it's 16N.

Can someone please explain this to me? Thank you.
