1. The problem statement, all variables and given/known data A uniform plate of mass m is suspended in the way shown. determine immediately after the connection at B has been released ;: A) angular aceleration of plate B) acceleration of its centre of mass 2. Relevant equations before b is detached t1 + t2 = mg (Linear equillibrium) t1 x c/2 = t2 x c/2 (rotational eqb) so t1 = t2 = mg/2 3. The attempt at a solution immediately after B is opened :: axis of rotation thru A. for Torque of mg = mg x c/2 .............1 also torque = Ia = moment of intertia x angular acceleration = (1/2 x m(c2 + c2/4) + 5mc2/4) x a so 'a' = 1.2g/c but that is not the answer. If you could please explain the Theory Involved and a general approach to solve the questions, i would be very thankful.
