(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

The mobile is in equilibrium. The fish B weighs

27 oz. Determine the weights of fish A, C and D.

(The weights of the crossbars are negligible).

2. Relevant equations

Moment = Force*Distance

3. The attempt at a solution

My idea here is to use the moments about each point, solve for one variable. Here is what I have com up with so far, am I on the right track?

D(14)=A(4) since their moments at that point are in equilibrium.

B(4)=12(A+D)

C(24)=6(A+B+D)

Am I wrong in setting it up this way?
