Not really sure if this is where this should be but oh well.(adsbygoogle = window.adsbygoogle || []).push({});

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.
