Homework Statement
(Sorry if I used any wrong term, English isn't my first language)
Be A (mass M) and B (mass m) two blocks connected to each other through an ideal wire passing through a wheel (caster), each block stays at one of the side of the wheel. If we apply a force F pointing up into the center of the wheel, which will be the acceleration of the wheel in terms of M, n, g and F? (Neglect the air resistance and the frictions).
Please, see the diagram:
Homework Equations
The Attempt at a Solution
It is wrong, I know, but I don't know why!
Be M > m
We have
Mg - T = M.a
T - mg = m.a
Thus, T = 2Mmg/(M+m)
So, the acceleration γ of the wheel should be F - 2T = (M+m).γ
γ = (F - 4Mmg)/(M+m)^2
Which is wrong...
