Not really sure if this is where this should be but oh well. 1. The problem statement, all variables and given/known data Image attached. It is given that: b = 200 mm mass = 6 kg Find the tension in cable A immediately after cord B is cut. 2. Relevant equations Moment = I*alpha + m*a*d F = ma? 3. The attempt at a solution I tried to do Moment about A = I*alpha (second part is zero?) , so 9.81*6*.1 = 1/6*6*2*.2^2*alpha I then solved for alpha. And plugged it into: Moment about G(center) = I*alpha, but this is wrong and I don't really understand why to be honest with you. It trips me up when the forces are not perpendicular to the center for some reason. The final answer is T = 23.5 N. Thanks.
