Homework Statement
Two blocks of mass m are suspended on the ends of a rigid weightless rod of length L1 + L2; With L1=20 cm and L2= 80 cm. The rod is held horizontally on the fulcrum shown in the diagram and then released. Calculate the accelerations of the two blocks as they start to move
Homework Equations
Mtot(total torque) = M1 + M2
M1 = l1*T
M2 = -l2*T
Mtot = Itot (total moment of inertia) * α (angular acceleration)
(T is the tension)
The Attempt at a Solution
I've really thought on it but i can think of nothing if not that i will have to use those formulaes to resolve it...
I thought that as the two masses are equal, even the two tensions are equal so T1=T2=T
The forces that causes the rod to rotate are T1 and T2 and act on the ends but i don't know how to find those and actually can't understand if that's what really happens.
I am really looking forward help as I'm having serious problems with that, i hope that someone will be able to help.
Thank you very much
